no.

Note that your AFS volume quota != AFS Cache Size.  What I want to
know is the output of:

        df /usr/vice/cache

The fact that your personal quota was increased from 100M to 200M is
irrelevant to the size of your cache.  The size of your cache only
matters in so far as the amount of data you can cache and reuse
without going back to the server.  There are tradeoffs for larger
caches.  In particular, the larger the cache, the larger the overhead.
However, the larger the cache, the more files you cacn store
locally....

Yes.

The entire directory...  (modulo the AFS Cache, but you probably
want to clean out the cache, too.)

You probably want:
        rm -rf /usr/vice/etc
        rm -f /usr/vice/cache/*Items

No.  The kernel-source RPM is just that.. _SOURCE_.  You still need to
follow these instructions to build the kernel module for your kernel.
I'm just trying to make sure you're using known-to-work packages in
order to limit the problem.

Worst case, you may need to "downgrade" to 2.4.18-X... Is that an
option for you (why are you running 2.4.19)?
