FC4: trashed /var partition, how to rebuild
|

| somehow i trashed my entire /var partition - restoring superblocks from
backup only accelerated its demise. i can use rescue disc to do anything
with all the rest of my partitions, but i cannot boot even after
redirecting /var to a new, empty folder (not mount) - the missing file
structure and run + log files are not recreated.
i've been researching how one might go about rebuilding /var from nothing,
and about the only lead i have is a program called mtree from BSD. i
haven't found any info about a linux port, much less one for my distro.
is there any program analagous to mtree for fedora?
maybe there's another way to avoid reinstalling the OS, but i'm at a loss.
thanks in advance

I assume you fsck the partition.
Does the orignal HD /var and sub-folders have the right uid, gid and
permissions? You change all permissions to ugo+rwx
Have you tried copying the /var structure and files from the rescue disk
to the new /var on the unmounted install changing HD /var to the right
permissions?
