* Moved helpers, common and triggers dirs into xbps-src, where
they belong.
* Renamed the templates dir to srcpkgs, it was so redundant before.
* Make it possible to add subpkgs with no restriction in names, for
example udev now has a subpkgs called "libgudev". Previously
subpkgs were named "${sourcepkg}-${pkgname}".
* xbps-src: changed to look for template files in current directory.
That means that most arguments from the targets have been removed.
* xbps-src: added a reinstall target, to remove + install.
* xbps-src: do not overwrite binpkgs by default, skip them.
And more that I forgot because it's a mega-commit that I've been
working for some days already...

.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
|
