Comment 2 James Laska 2011-05-12 07:52:35 EDT
The reproducer here was pxebooting into the default cobbler kickstart install.  I believe cobbler is adding BOOTIF= and doing a text-mode kickstart install.  Looks like it is trying to get the LVM VG name from the system hostname, but that data may not yet be available?
Comment 3 Radek Vykydal 2011-05-12 08:08:53 EDT
The cause is having ksdevice=bootif without BOOTIF= provided (by pxe). This patch on master would fix it:
Comment 4 James Laska 2011-05-12 08:25:25 EDT
Ah, thanks Radek.  This seems like a straightforward fix, I'd like to propose this for F15.  

Since there is a workaround present (provide BOOTIF=), I don't believe this is a MUSTHAVE blocker fix for F15.  However, it seems perfectly sensible to include if anaconda should be rebuilt.  And considering this can't be fixed post-release, and is of limited scope, I'm all for it :)

+0 Blocker, +1 NTH

Any other votes?

Yes, seems safe, it is in master and rhel6.1 so it is also quite tested.

Discussed during 2011-05-16 Fedora QA blocker review meeting [1].  Accepted as NTH for F15.  Should an anaconda respin be required, this bug can be included in an updated anaconda package.  Otherwise, no action is required.
