f16 alpha rc5 softraided /boot

[Rudolf Kastl]

Hello!

below are two bugs for getting softraided (raid level 1)  /boot to
work properly with f16 alpha rc5:

https://bugzilla.redhat.com/show_bug.cgi?id=732164
https://bugzilla.redhat.com/show_bug.cgi?id=732441

left to test:

* softraiding two disks as mirror and putting an lvm on top... then
put /boot into logical volume that sits on a softraid. in theory that
should work too. didnt have time to try it yet
* checking if anaconda writes the bootloader to both disks (last time
i tried it didnt)

kind regards,
Rudolf Kastl
