Fyi. On one of my cauldron installs, I have /usr in a lvm
logical volume. In order to get this to be bootable, I
modified /etc/dracut.conf to have
add_drivers+="dm_mod dm_crypt"
and
install_items+=(/bin/grep /lib/libpcre.so.0.0.1 /lib/libpcre.so.0 /lib/libdevmapper-event.so.1.02 /lib/libdevmapper.so.1.02 /lib/libreadline.so.6 /lib/libncurses.so.5 /sbin/lvm /lib/modules/3.1.4-server-1.mga2/kernel/drivers/md/dm-crypt.ko.gz /lib/modules/3.1.4-server-1.mga2/kernel/drivers/md/dm-mod.ko.gz /sbin/dmsetup /sbin/lsmod )
I modified /usr/share/dracut/modules.d/98usrmount/mount-usr.sh to have ...
#!/bin/sh
# -*- mode: shell-script; indent-tabs-mode: nil; sh-basic-offset: 4; -*-
# ex: ts=8 sw=4 sts=4 et filetype=sh
type info >/dev/null 2>&1 || . /lib/dracut-lib.sh
type fsck_single >/dev/null 2>&1 || . /lib/fs-lib.sh
mount_usr()
{
local _dev _mp _fs _opts _rest _fs_found _ret _mount_point
if ! __fgrep "device-mapper" /proc/devices >/dev/null 2>&1 ; then
modprobe dm-mod >/dev/null 2>&1

fi
)
_mount_point="usr"; fsck_mount
_mount_point="var"; fsck_mount
_mount_point="var/mnt"; fsck_mount

}
mount_usr
I initially only had the /usr being mounted, but found that when it
got around to trying to mount the next lv, it would report that the
mount timed out due to a dependency failure, but with no indication
of why. I ended up modifying the script to mount all of my lvm
partitions, in the initramfs, to get it to work.
