Comment # 7 on bug 971023 from Andreas Stieger

Hmm, as this sounds like a initrd problem, I'll try to assign this one to
dracut bugowners.

As this system booted once and then failed to boot after an update, the
following would be relevant:

* output of "mkinitrd -v" in a system that still works.

Can you try to manually call mkinitrd before the breaking reboot?

Using the DVD, can you try do the following:

* boot the rescue system
* cryptsetup luksOpen / open .. as required
* mount your system (/, /boot, /var) into a tree under /mnt, /mnt/boot,
/mnt/var
* for X in proc dev sys; do mount --bind /$X /mnt/$X
* chroot /mnt
* mkinitrd -v

and attach the output?
