[Test-Announce] PSA: Don't install kernels with grubby 8.35-6.fc21 - they won't boot

Hi, folks. I've just noticed that grubby 8.35-6.fc21 made it to the
updates-testing repository. That build has a rather bad bug - when it
writes grub entries it will likely leave out the 'initrd16' (or just
'initrd', depending how old your system is) line, which will probably
mean the kernel won't boot.

So, best downgrade to 8.35-4.fc21 (from the 'fedora' repo) or upgrade to
(https://admin.fedoraproject.org/updates/FEDORA-2014-12932/grubby-8.35-7.fc21 , should hit updates-testing soon, you can get it from koji or with 'bodhi -D FEDORA-2014-12932' for now) before installing any kernels.

If you do wind up with a grubby 8.35-6 installed kernel which won't
boot, don't panic. You can manually add the required line by copying
from the line for an older kernel and just changing the filename
appropriately - it should come right under the 'linux' / 'linux16' line.

You can also just boot an older kernel, remove the newer kernel, upgrade
or downgrade grubby, and install the newer kernel again.

Sorry for the trouble!
