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
