Yes, there is a kernel installed, a stock f7, off-the-net live image was
used. Think I found the issue, in kernelVersionList
ts = rpm.TransactionSet() is looking at the running system and not at
the newly installed image. Changing that line to
ts = rpm.TransactionSet("/mnt/sysimage") results in a db version
mismatch error when run from the "normal" installer but not when run
from the livecd, but if I do a "rm -f /mnt/sysimage/var/lib/rpm/__db.*"
before calling kernelVersionList, in the installer, I get a new initrd,
grub.conf, it all works. :-)
I'm just not sure why there is the db version mis-match between the
livecd and the "normal" installer. I'll leave that for another time to
figure out.
