Support having root on LUKS with the password prompting handled by plymouth.
This requires ensuring our input is from /dev/console and also requires that
we import vol_id info about all block devices rather than ignoring dm devs
(which is what the persistent storage rules do by default)
Add basic support for the use of plymouth in the new initrd world. Also
includes a hack at the moment to install from a local plymouth tree to make
testing easier
For LVM, we need to do activation of the volume group within the initrd.
Stick lvm tools into the initrd as well as a (basic and stupid) udev rule
to run vgchange -ay. Ultimately we want to get a better rule for this into
udev proper
First pass at a new initrd implementation. Right now, it's a very simple
/init and we use nash's switchroot command via switch_root. The idea is to
get a switchroot binary into util-linux that can be used instead
generate.sh will let you generate an initrd image. Note that the generator
is intentionally super simple right now and is an area that will need a lot
of work once we're happier with how the /init process runs
