Now is not problem with serial console.

loglevel=3 will remove warnings about ACPI errors and processor
vulnerabilities. These messages break silent boot and scare users.
However, we cannot correct these errors.
'loglevel=3' must be after 'quiet'. Otherwise, errors are shown.

When installing with a classic installer, this package is also needed.

use/plymouth/vm is not needed, because use/plymouth/base is the
target that needs to be achieved when building the vm image.

Needed for make-initrd >= 2.25.0

THE_PACKAGES_REGEXP must have a regular expression, otherwise it
doesn't differ from THE_PACKAGES.
Since there have been no problems so far, then regexp is not needed.

This needed for live.

The drm feature solves the problem of creating a common entry
point for adding kernel drm modules for different package lists.
The need for allocation into a separate feature arose from one
parties to the need to make a switch between free and proprietary
NVIDIA driver, on the other, because of the need to add only drm
modules kernels for purposes such as use/stage2/kms and use/plymouth.

Also no more switch needed for RADEON, as only the free video driver
remains.

make-initrd-plymouth missing in squashfs results in
plymouth bootsplash not available at boot.

This has only been useful for plymouth feature,
and +installer shortcut included this target
for all the wrong reasons as it seems today
(thus blocking the DRM-free server installers,
for example).

The missing "; @:" at the end of the otherwise recipeless rule
resulted in target graph being broken; I should have checked this
when introducing these aliases (the intent was to reduce noise).

It's configured by plymouth feature when needed;
install2 bootargs support is generalized a bit
to become stage2 one as was intended anyways.

An initial draft of it was done half a year ago but several tricky
thingies had kept the code from showing up as it was rather brittle
and incomplete.

This implementation involves quite a few changes all over the place
but finally works good enough for live and installer images.

Please pay attention to the versions of these packages:
- installer-feature-setup-plymouth (0.3.2-alt1+)
- branding-altlinux-sisyphus (20110706-alt2+ if used)
- plymouth (0.8.3-alt20.git20110406+)
