initramfs-tools: add sources and use them.
* Add source files directly to avoid recreating patches and patches lots of times with no gain. * Add du and expr busybox symlinks at init time. Bump revision. --HG-- extra : convert_revision : 4928750b0110f43cde577f6068e79bd0675c64cf

.TH INITRAMFS-TOOLS 8 "2009/02/23" "Linux" "mkinitramfs script overview"
|
||||
|
||||
.SH NAME
|
||||
initramfs-tools \- an introduction to writing scripts for mkinitramfs
|
||||
|
||||
.SH DESCRIPTION
|
||||
initramfs-tools has one main script and two different sets of subscripts which
|
||||
will be used during different phases of execution. Each of these will be
|
||||
discussed separately below with the help of an imaginary tool which performs a
|
||||
frobnication of a lvm partition prior to mounting the root partition.
|
||||
|
||||
Valid boot and hook scripts names consist solely of alphabetics, numerics
|
||||
and underscores. Other scripts are discarded.
|
||||
|
||||
.SS Hook scripts
|
||||
These are used when an initramfs image is created and not included in the
|
||||
image itself. They can however cause files to be included in the image.
|
||||
|
||||
.SS Boot scripts
|
||||
These are included in the initramfs image and normally executed during
|
||||
kernel boot in the early user-space before the root partition has been
|
||||
mounted.
|
||||
|
||||
.SH INIT SCRIPT
|
||||
The script which is executed first and is in charge of running all other
|
||||
scripts can be found in /usr/share/initramfs-tools/init. It takes a number of
|
||||
arguments which influence the boot procedure:
|
||||
|
||||
.SS Boot options
|
||||
|
||||
The init and root are usually passed by the boot loader for local boot.
|
||||
The other parameters are optional.
|
||||
|
||||
.TP
|
||||
\fB\fI init
|
||||
the binary to hand over execution to on the root fs after the initramfs scripts are done.
|
||||
|
||||
.TP
|
||||
\fB\fI root
|
||||
the device node to mount as the root file system.
|
||||
The recommended usage is to specify the UUID as followed "root=UUID=xxx".
|
||||
As normal device names are not stable and may change depending on the
|
||||
boot order.
|
||||
|
||||
.TP
|
||||
\fB\fI rootdelay
|
||||
set delay in seconds. Determines how long mountroot waits for root to appear.
|
||||
The default is 180 seconds.
|
||||
|
||||
.TP
|
||||
\fB\fI rootflags
|
||||
set the file system mount option string.
|
||||
|
||||
.TP
|
||||
\fB\fI rootfstype
|
||||
set the root file system type.
|
||||
|
||||
.TP
|
||||
\fB\fI nfsroot
|
||||
can be either "auto" to try to get the relevant information from DHCP or a
|
||||
string of the form NFSSERVER:NFSPATH or NFSSERVER:NFSPATH:NFSOPTS.
|
||||
Use root=/dev/nfs for NFS to kick to in. NFSOPTS can be looked up in
|
||||
\fInfs(5)\fP.
|
||||
|
||||
.TP
|
||||
\fB\fI ip
|
||||
tells how to configure the ip address. Allows to specify an different
|
||||
NFS server than the DHCP server. See Documentation/nfsroot.txt in
|
||||
any recent Linux source for details. Optional paramater for NFS root.
|
||||
|
||||
.TP
|
||||
\fB\fI cryptopts
|
||||
passes the args for cryptoroot. Set by the cryptsetup boot hooks.
|
||||
|
||||
.TP
|
||||
\fB\fI boot
|
||||
either local or NFS (affects which initramfs scripts are run, see the "Subdirectories" section under boot scripts).
|
||||
|
||||
.TP
|
||||
\fB\fI resume
|
||||
On install initramfs-tools tries to autodetect the resume partition. On success
|
||||
the RESUME variable is written to /etc/initramfs-tools/conf.d/resume.
|
||||
The boot variable noresume overrides it.
|
||||
|
||||
.TP
|
||||
\fB\fI resume_offset
|
||||
Specify the offset from the partition given by "resume=" at which the swap
|
||||
header of the swap file is located.
|
||||
|
||||
.TP
|
||||
\fB\fI quiet
|
||||
reduces the amount of text output to the console during boot.
|
||||
|
||||
.TP
|
||||
\fB\fI ro
|
||||
mounts the rootfs read-only.
|
||||
|
||||
.TP
|
||||
\fB\fI rw
|
||||
mounts the rootfs read-write.
|
||||
|
||||
.TP
|
||||
\fB\fI blacklist
|
||||
disables load of specific modules.
|
||||
Use blacklist=module1,module2,module3 bootparameter.
|
||||
|
||||
.TP
|
||||
\fB\fI panic
|
||||
sets an timeout on panic.
|
||||
panic=<sec> is a documented security feature: it disables the debug shell.
|
||||
|
||||
.TP
|
||||
\fB\fI debug
|
||||
generates lots of output. It writes a log to /dev/.initramfs/initramfs.debug.
|
||||
Instead when invoked with an arbitrary argument output is written to console.
|
||||
Use for example "debug=vc".
|
||||
|
||||
.TP
|
||||
\fB\fI break
|
||||
spawns a shell in the initramfs image at chosen run-time
|
||||
(top, modules, premount, mount, mountroot, bottom, init).
|
||||
The default is premount without any arg.
|
||||
Beware that if both "panic" and "break" are present,
|
||||
initramfs will not spawn any shells but reboot instead.
|
||||
|
||||
.TP
|
||||
\fB\fI all_generic_ide
|
||||
loads generic IDE/ATA chipset support on boot.
|
||||
|
||||
|
||||
.SH HOOK SCRIPTS
|
||||
|
||||
Hooks can be found in two places: /usr/share/initramfs-tools/hooks and
|
||||
/etc/initramfs-tools/hooks. They are executed during generation of the
|
||||
initramfs-image and are responsible for including all the necessary components
|
||||
in the image itself. No guarantees are made as to the order in which the
|
||||
different scripts are executed unless the prereqs are setup in the script.
|
||||
|
||||
.SS Header
|
||||
In order to support prereqs, each script should begin with the following lines:
|
||||
|
||||
.RS
|
||||
.nf
|
||||
#!/bin/sh
|
||||
PREREQ=""
|
||||

|
||||

|
||||

|
||||
# Begin real processing below this line
|
||||
.fi
|
||||
.RE
|
||||
|
||||
For example, if you are writing a new hook script which relies on lvm, the line
|
||||
starting with PREREQ should be changed to PREREQ="lvm" which will ensure that
|
||||
the lvm hook script is run before your custom script.
|
||||
|
||||
.SS Help functions
|
||||
/usr/share/initramfs-tools/hook-functions contains a number of functions which
|
||||
deal with some common tasks in a hook script:
|
||||
.TP
|
||||
\fB\fI
|
||||
manual_add_modules
|
||||
adds a module (and any modules which it depends on) to the initramfs image.
|

.TP
|

\fB\fI
|
||||
add_modules_from_file
|
||||
reads a file containing a list of modules (one per line) to be added to the
|
||||
initramfs image. The file can contain comments (lines starting with #) and
|
||||
arguments to the modules by writing the arguments on the same line as the name
|
||||
of the module.
|
||||
.RS
|
||||

.TP
|
||||
\fB\fI
|
||||
force_load
|
||||
adds a module (and its dependencies) to the initramfs image and also
|
||||
unconditionally loads the module during boot. Also supports passing arguments
|
||||
to the module by listing them after the module name.
|
||||
.RS
|
||||

copy_modules_dir
|
||||

|
||||
initramfs image.
|
||||
.RS
|
||||
.PP
|
||||

|
||||
.SS Including binaries
|
||||
If you need to copy binaries to the initramfs module, a command like this
|
||||
should be used:
|
||||
.PP
|
||||
.RS
|
||||
copy_exec /sbin/mdadm /sbin
|
||||
.RE
|
||||
|
||||
mkinitramfs will automatically detect which libraries the executable depends on
|
||||
and copy them to the initramfs. This means that most executables, unless
|
||||
compiled with klibc, will automatically include glibc in the image which will
|
||||
increase its size by several hundred kilobytes.
|
||||
|
||||
.SS Exported variables
|
||||
mkinitramfs sets several variables for the hook scripts environment.
|
||||
|
||||
.TP
|
||||
\fB\fI MODULESDIR
|
||||
corresponds to the linux-2.6 modules dir.
|
||||
.TP
|
||||
\fB\fI version
|
||||
is the $(uname -r) linux-2.6 version against mkinitramfs is run.
|
||||
.TP
|
||||
\fB\fI CONFDIR
|
||||
is the path of the used initramfs-tools configurations.
|
||||
.TP
|
||||
\fB\fI DESTDIR
|
||||
is the root path of the newly build initramfs.
|
||||
.TP
|
||||
\fB\fI DPKG_ARCH
|
||||
allows arch specific hook additions.
|
||||
.TP
|
||||
\fB\fI verbose
|
||||
corresponds to the verbosity of the update-initramfs run.
|
||||
.TP
|
||||
\fB\fI KEYMAP
|
||||
sets if a keymap needs to be added to initramfs.
|
||||
.TP
|
||||
\fB\fI MODULES
|
||||
specifies which kind of modules should land on initramfs.
|
||||
This setting shouldn't be overriden by hook script, but can guide them
|
||||
on how much they need to include on initramfs.
|
||||
|
||||
|
||||
.SH BOOT SCRIPTS
|
||||
|
||||
Similarly to hook scripts, boot scripts can be found in two places
|
||||
/usr/share/initramfs-tools/scripts/ and /etc/initramfs-tools/scripts/. There
|
||||
are a number of subdirectories to these two directories which control the boot
|
||||
stage at which the scripts are executed.
|
||||
|
||||
.SS Header
|
||||
Like for hook scripts, there are no guarantees as to the order in which the
|
||||
different scripts in one subdirectory (see "Subdirectories" below) are
|
||||
executed. In order to define a certain order, a similar header as for hook
|
||||
scripts should be used:
|
||||
|
||||
.RS
|
||||
.nf
|
||||
#!/bin/sh
|
||||
PREREQ=""
|
||||
prereqs()
|
||||
{
|
||||
echo "$PREREQ"
|

.TP
|

\fB\fI
|

init-bottom) after modules specified by hooks and /etc/initramfs-tools/modules
|

have been loaded.
|

.TP
|

\fB\fI
|

\fB\fI
|

.SS Exported variables
|

init sets several variables for the boot scripts environment.
|
||||
|
||||
.TP
|
||||
\fB\fI ROOT
|
||||
correponds to the root boot option.
|
||||
Advanced boot scripts like cryptsetup or live-initramfs need to play tricks.
|
||||
Otherwise keep it alone.
|
||||
.TP
|
||||
\fB\fI ROOTDELAY, ROOTFLAGS, ROOTFSTYPE, IP
|
||||
correponds to the rootdelay, rootflags, rootfstype or ip boot option.
|
||||
.TP
|
||||
\fB\fI DPKG_ARCH
|
||||
allows arch specific boot actions.
|
||||
.TP
|
||||
\fB\fI blacklist, panic, quiet, resume, noresume, resume_offset
|
||||
set according relevant boot option.
|
||||
.TP
|
||||
\fB\fI break
|
||||
Useful for manual intervention during setup and coding an boot script.
|
||||
.TP
|
||||
\fB\fI init
|
||||
passes the path to init(8) usually /sbin/init.
|
||||
.TP
|
||||
\fB\fI readonly
|
||||
is the default for mounting the root corresponds to the ro bootarg.
|
||||
Overriden by rw bootarg.
|
||||
.TP
|
||||
\fB\fI rootmnt
|
||||
is the path where root gets mounted usualy /root.
|
||||
.TP
|
||||
\fB\fI debug
|
||||
indicates that a debug log is captured for further investigation.
|
||||
|
||||
|
||||
.SH DEBUG
|
||||

.TH INITRAMFS.CONF 5 "2008/12/19" "Linux" "initramfs.conf manual"
|

|
||||
.SH NAME
|
||||
initramfs.conf \- configuration file for mkinitramfs
|
||||
|
||||
.SH DESCRIPTION
|
||||
The behaviour of
|
||||
.B mkinitramfs
|
||||
can be modified by its configuration file.
|
||||
|
||||
Each line in the file can be a configuration variable, a blank line,
|
||||
or a comment. The value of an variable is assigned by an statement
|
||||
of the form: \fIname\fP=[\fIvalue\fP]
|
||||
|
||||
Configuration options can be broken out into configuration snippets and
|
||||
placed in individual files in the /etc/mkinitramfs/conf.d directory. Files
|
||||
in this directory are always read \fBafter\fP the main configuration file,
|
||||
so you can override the settings in the main config file without editing it
|
||||
directly.
|
||||
|
||||
.SH GENERAL VARIABLES
|
||||
.TP
|
||||
\fB MODULES
|
||||
Specifies the modules for the initramfs image.
|
||||
The default setting is \fImost\fP.
|
||||
|
||||
\fImost\fP adds all the framebuffer, acpi, file system, ide, sata, scsi and usb drivers.
|
||||
|
||||
\fIdep\fP tries to guess which modules are necessary for the running box.
|
||||
|
||||
\fInetboot\fP adds the base modules, network modules, but skips block devices.
|
||||
|
||||
\fIlist\fP includes only modules from the additional modules list to load them
|
||||
early.
|
||||
|
||||
.TP
|
||||
\fB BUSYBOX
|
||||
Include busybox utilities for the boot scripts.
|
||||
If set to 'n'
|
||||
.B mkinitramfs
|
||||
will build an initramfs without busybox.
|
||||
Beware that many boot scripts need busybox utilities.
|
||||
|
||||
.TP
|
||||
\fB KEYMAP
|
||||
If set to 'y', the console keymap will be loaded during the initramfs stage.
|
||||
The keymap will anyway be loaded by the initscripts later, and the packages
|
||||
that might need input will normally set this variable automatically, so there
|
||||
should normally be no need to set this.
|
||||
|
||||
.SH NFS VARIABLES
|
||||
.TP
|
||||
\fB BOOT
|
||||
Allows to use an nfs drive as the root of the drive.
|
||||
The default is to boot from \fIlocal\fP media (hard drive, USB stick).
|
||||
Set to \fInfs\fP for an NFS root share.
|
||||
|
||||
.TP
|
||||
\fB DEVICE
|
||||
Specifies the network interface, like eth0.
|
||||
|
||||
.TP
|
||||
\fB ROOT
|
||||
Allows optional root bootarg hardcoding, when no root bootarg can be passed.
|
||||
A root bootarg overrides that special setting.
|
||||
|
||||
.TP
|
||||
\fB NFSROOT
|
||||
Defaults to \fIauto\fP in order to pick up value from DHCP server.
|
||||
Otherwise you need to specify \fIHOST:MOUNT\fP.

|
||||
|
||||
.SH DESCRIPTION
|
||||
The
|
||||
.B mkinitramfs
|
||||
script generates an initramfs image.
|
||||
The initramfs is a gzipped cpio archive. The archive can be used on a
|
||||
different box of the same arch with the corresponding Linux kernel.
|
||||
.B mkinitramfs
|
||||
is meant for advanced usage. On your local box
|
||||
.B update-initramfs
|
||||
calls
|
||||
.B mkinitramfs
|
||||
with the relevant parameters.
|
||||
.B update-initramfs
|
||||
keeps sha1sum of generated initramfs. It takes care to generate backups
|
||||
and eventually runs the bootloader.
|
||||
|
||||
At boot time, the kernel unpacks that archive into RAM disk, mounts and
|
||||
uses it as initial root file system. All finding of the root device
|
||||
happens in this early userspace.
|
||||
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
\fB \-d \fI confdir
|
||||
Set an alternate configuration directory.
|
||||
|
||||
.TP
|
||||
\fB \-k
|
||||
Keep the temporary directory used to make the image.
|
||||
|
||||
.TP
|
||||
\fB \-o \fI outfile
|
||||
Write the image to
|
||||
.IR outfile .
|
||||
|
||||
.TP
|
||||
\fB \-r \fI root
|
||||
Override the
|
||||
.B ROOT
|
||||
setting in
|
||||
.IR initramfs.conf .
|
||||
|
||||
.TP
|
||||
\fB \-v
|
||||
Set the verbose mode output.
|
||||
|
||||
.TP
|
||||
\fI version
|
||||
Set the kernel version of the initramfs image
|
||||
(defaults to the running kernel).
|
||||
|
||||
.TP
|
||||
\fB\-\-supported-host-version=\fIhversion
|
||||
This option queries if mkinitramfs can create ramdisks on a running kernel of version
|
||||
.IR hversion .
|
||||
|
||||
.TP
|
||||
\fB\-\-supported-target-version=\fItversion
|
||||
This option queries if mkinitramfs can create ramdisks for kernel version
|
||||
.IR tversion .
|
||||
|
||||
.SH FILES
|
||||
.TP
|
||||
.I /etc/initramfs-tools/initramfs.conf
|
||||
The default configuration file for the script. See
|
||||
.BR initramfs.conf (5)
|
||||
for a description of the available configuration parameter.
|
||||
|
||||
.TP
|
||||
.I /etc/initramfs-tools/modules
|
||||
Specified modules will be put in the generated image and loaded when the system boots. The format - one per line - is identical to that of
|
||||
.I /etc/modules,
|
||||
which is described in
|
||||
.BR modules (5).
|
||||
|
||||
.TP
|
||||
.I /etc/initramfs-tools/conf.d
|
||||
The conf.d directory allows to hardcode bootargs at initramfs build time
|
||||
via config snippets. This allows to set ROOT or RESUME.
|
||||
This is especially useful for bootloaders, which do not pass an root bootarg.
|
||||
|
||||
.TP
|
||||
.I /etc/initramfs-tools/DSDT.aml
|
||||
If this file exists, it will be appended to the initramfs in a way that causes
|
||||
it to be loaded by ACPI.
|
||||
|
||||
.SH EXAMPLES
|
||||
|
||||
Create an initramfs for current running kernel:
|
||||
|
||||
.PP
|
||||
.B mkinitramfs -o ~/tmp/initramfs-$(uname -r)
|
||||
|
||||
Create an initramfs for specific kernel and keep builddirs:
|
||||
|
||||
.PP
|
||||
.B mkinitramfs -k -o ~/tmp/initramfs-2.6.21-686 2.6.21-686
|
||||
|
||||
Debug initramfs creation (check out written logfile)
|
||||
.PP
|
||||
.B sh -x mkinitramfs -o ~/tmp/initramfs-$(uname -r) 2> ~/tmp/log
|
||||

|
||||

.TH UPDATE-INITRAMFS 8 "2008/12/19" "Linux" "update\-initramfs manual"
|
||||
|
||||
.SH NAME
|
||||
update\-initramfs \- generate an initramfs image
|
||||
|
||||
.SH SYNOPSIS
|
||||
.B update\-initramfs
|
||||
.RB \-c | \-d | \-u
|
||||
.RB [ \-k
|
||||
.IR version ]
|
||||
.RB [ \-t ]
|
||||
.RB [ \-v ]
|
||||
.RB [ \-b ]
|
||||
.RB [ \-h ]
|
||||
.SH DESCRIPTION
|
||||
The
|
||||
.B update\-initramfs
|
||||
script manages your initramfs images on your local box.
|
||||
It keeps track of the existing initramfs archives in /boot.
|
||||
There are three modes of operation create, update or delete.
|
||||
You must at least specify one of those modes.
|
||||
|
||||
The initramfs is a gzipped cpio archive.
|
||||
At boot time, the kernel unpacks that archive into RAM disk, mounts and
|
||||
uses it as initial root file system. All finding of the root device
|
||||
happens in this early userspace.
|
||||
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
\fB \-k \fI version
|
||||
Set the specific kernel version for whom the initramfs will be generated.
|
||||
For example the output of uname \-r for your currently running kernel.
|
||||
This argument is optional for update. The default is the latest kernel version.
|
||||
|
||||
The use of "all" for the
|
||||
.I version
|
||||
string specifies
|
||||
.B update\-initramfs
|
||||
to execute the chosen action for all kernel versions, that are already known
|
||||
to
|
||||
.B update\-initramfs.
|
||||
|
||||
.TP
|
||||
\fB \-c
|
||||
This mode creates a new initramfs.
|
||||
|
||||
.TP
|
||||
\fB \-u
|
||||
This mode updates an existing initramfs.
|
||||
|
||||
.TP
|
||||
\fB \-d
|
||||
This mode removes an existing initramfs.
|
||||
|
||||
.TP
|
||||
\fB \-t
|
||||
Allows to take over an custom initramfs with a newer one.
|
||||
|
||||
.TP
|
||||
\fB \-v
|
||||
This option increases the amount of information you are given during
|
||||
the chosen action.
|
||||
|
||||
.TP
|
||||
\fB \-b
|
||||
Set an different bootdir for the image creation.
|
||||
|
||||
.TP
|
||||
\fB \-h
|
||||
Print a short help page describing the available options in
|
||||
.B update\-initramfs.
|
||||
|
||||
.SH EXAMPLES
|
||||
|
||||
Update the initramfs of the newest kernel:
|
||||
|
||||
.PP
|
||||
.B update\-initramfs -u
|
||||
|
||||
|
||||
Create the initramfs for a specific kernel:
|
||||
|
||||
.PP
|
||||
.B update\-initramfs -c -k 2.6.18-1-686
|

Setting it to \fIall\fP updates any known initramfs.
|
||||
It is possible to set it to \fIno\fP for remote servers or boxes where
