Last Kernel update left me without initramfs

[Federico Marziali]

Hi all,

with Fedora 13, the last kernel update left me without the file
intirmafs in the /boot partition. All the rest is there, and I was
wondering if there is an easy way to build this file myself... Any
tutorial available for fedora?
I tried to use the previous kernel file just by renaming it but it
won't work. I get an error from iptables (can't have the slightest
idea why) and from the nvidia drivers (this I guess since I installed
the new ones together with the last kernel, so the old intiramfs has
some reference to the old nvidia drivers module??)

Any hint appreciated.
Otherwise, I would just wait a couple of days and installa Fedora
14... although this seems to me a very windows-approach style :)

BTW, can someone explain to me what checks are being made by yum to
ensure that this doesn't happen?

Thanks in advance,
Fede
