* 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...

# This script is run inside of the initramfs environment during the
|
|
# system boot process. It is installed there by 'mkinitramfs'. The
|
|
# package that owns it may opt to install it in either an appropriate
|
|
# location under "/usr/share/initramfs-tools/scripts/", or a similar
|
|
# location under "/etc/mkinitramfs/scripts/", depending upon whether
|
|
# it should be considered to be a user modifiable conffile or not.

# TODO: How do we deal with the case where the package that installed
|
|
# this has been removed but not purged, if we always arbitrarily

# * It is expected that /proc and /sys will be umounted before
|
|
# changing over to the real root file system, so you must not keep
|
|
# any files open on them beyond these scripts.
|
|
#
|
|
# * You may like to strip these documentation comments from this
|
|
# example if you take it for a template, to save a little space in
|

# the initramfs, since nobody will ever read it from inside of
