kernel panic during boot
Description of problem:
I did an install of F18 Alpha TC5 i686 Live, all defaults. After reboot, I see:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
If I see grub menu, it has root=/dev/vda3 (is that correct for default anaconda install?), but it seems to lack any initrd item.
Version-Release number of selected component (if applicable):
F18 Alpha TC5 i686 Live
Steps to Reproduce:
1. install live using defaults

Proposing as a blocker:
" In most cases (see Blocker_Bug_FAQ), a system installed according to any of the above criteria (or the appropriate Beta or Final criteria, when applying this criterion to those releases) must boot to the 'firstboot' utility on the first boot after installation, without unintended user intervention, unless the user explicitly chooses to boot in non-graphical mode. This includes correctly accessing any encrypted partitions when the correct passphrase is supplied. The firstboot utility must be able to create a working user account "
+1 blocker per criterion cited.
We need log files in order to debug installation problems.

program.log has 10MB, so I had to compress it. It is really intended to list every file on the filesystem in that log?
Anaconda calls grub2-mkconfig. But since there is only initrd-plymouth.img, which is ignored by grub2-mkconfig. Maybe anaconda should call 'dracut -f' in chroot before running grub2-mkconfig?
Discussed at 2012-09-05 blocker review meeting. Accepted as a blocker per criterion "In most cases, a system installed according to any of the above criteria must boot to the 'firstboot' utility on the first boot after installation, without unintended user intervention, unless the user explicitly chooses to boot in non-graphical mode. The firstboot utility must be able to create a working user account".
