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 Fedora and 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.
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.
