Debugging
Create your image with the debug module:
# dracut -a debug /boot/test-$(uname -r) $(uname -r)
Add "rdshell" to the kernel command line, remove "rhgb" and "quiet" and boot the image.
Once you are dropped to a shell do:
# dmesg|grep dracut
Add the output and your kernel command line to the bug report.

What's new in dracut-0.5:
- more generic (all plymouth modules, all keyboards, all console fonts)
- more kernel command line parameters (see also man dracut(8))
- a helper tool, which generates the kernel command line
(dracut-gencmdline)
for my machine this looks like this: # /sbin/dracut-gencmdline rd_DM_UUID=nvidia_dddhfead rd_LUKS_UUID=luks-227fe0ce-7e8c-453a-823f-d5bf34ca1da3 rd_LVM_VG=VolGroup00 KEYBOARDTYPE=pc KEYTABLE=de-latin1 SYSFONT=latarcyrheb-sun16 LANG=en_US.UTF-8
If you have encrypted partitions you should at least set "KEYTABLE" to have the correct keyboard setting.
rd_DM_UUID, rd_LUKS_UUID, rd_MD_UUID help you, if dracut does more than you want in its automatic mode. So if you want to be more specific on what dracut is allowed to assemble, uncrypt etc. just specify the exact parameters.
For those with an Intel fake software raid onboard (imsm/isw), you might not want MD handle those, but fallback to the old behaviour with DM. To do so add rd_NO_MDIMSM to the kernel command line.
New kernel command line parameters:
I18N e.g. LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=de-latin1-nodeadkeys
KEYBOARDTYPE=sun|pc will be written to /etc/sysconfig/keyboard in the initramfs
KEYTABLE=<keytable filename> will be written to /etc/sysconfig/keyboard in the initramfs
SYSFONT= Console font will be written to /etc/sysconfig/i18n in the initramfs
SYSFONTACM= Unicode font map will be written to /etc/sysconfig/i18n in the initramfs
UNIMAP= Unicode font map will be written to /etc/sysconfig/i18n in the initramfs
LANG=<locale> will be written to /etc/sysconfig/i18n in the initramfs
Bootsplash - plymouth rd_plytheme=<theme name> specify the plymouth bootsplash theme (fallback is text)
LVM rd_NO_LVM disable LVM detection
rd_LVM_VG=<volume group name> only activate the volume groups with the given name
crypto LUKS rd_NO_LUKS disable crypto LUKS detection
rd_LUKS_UUID=<luks uuid> only activate the LUKS partitions with the given UUID
MD rd_NO_MD disable MD RAID detection
rd_NO_MDIMSM no MD RAID for imsm/isw raids, use dmraid instead
rd_MD_UUID=<md uuid> only activate the raid sets with the given UUID
DMRAID rd_NO_DM disable DM RAID detection
rd_DM_UUID=<dmraid uuid> only activate the raid sets with the given UUID
