I can tell you how mine is set up.

These are the packages that would be merged, in order:
[ebuild R ~] sys-kernel/dracut-013-r2 USE="-debug (-selinux)"
DRACUT_MODULES="btrfs crypt lvm -biosdevname -caps -crypt-gpg -dmraid -
dmsquash-live -gensplash -iscsi -livenet -mdraid -multipath -nbd -nfs -
plymouth -syslog -xen" 0 kB
I don't use any of the other modules so all I enable are btrfs, crypt and
lvm.
/etc/dracut.conf has no changes from the default except for the line:
add_dracutmodules+="crypt dm lvm"
but I'm about 80% sure even that isn't necessary and you could just leave
the default values alone. One of these days I'll get around to testing that.
I make an initramfs with the following command:
dracut --lzma<hostname>.dracut.lzma<kernel version>
(obviously change --lzma to whatever type of compression your kernel
expects
to use and name the file whatever you want. Make sure to include the kernel
version just like it appears in your /lib/modules/ directory so that dracut
includes the correct kernel modules)
Then I make grub.conf look something like this:
root (hd0,0)
kernel /<hostname> root=UUID=08b00d7f-b633-4c03-98fe-dd5942a8fb7e
initrd /<hostname>.dracut.lzma
I like to name my kernels and initramfs files by the hostname of the
computer since I have three that I manage but use whatever you want and
just
make sure you put the right filenames in grub.conf.
You can obtain the UUID of your root filesystem by a number of methods, but
the easiest is to use ls -l /dev/disks/by-uuid/
That's really all there is to it. Dracut will boot up and load the modules
it is compiled with and search through the disks, logical volumes, and
dmcrypt containers until it finds a filesystem with the UUID you specify.
Once it finds the root filesystem it mounts it with whatever options you've
specified in /etc/fstab and then hands control over to OpenRC.
If it has the necessary modules (kernel and dracut) and you pass the right
root= option then it Just Works.

I'm going to give this way a shot next time. I'm downloading a lot of
TV shows right now so can't reboot very often.
Thanks much for posting this tho. This helps me a LOT. With all the
time I have on my hands, I really need to learn how to add things to all
these wiki sites.
