For a cache partition, at least on other *ixes, the cache partition
has always needed special attention because of the way its used by
the
AFS kernel module. Certain care has to be taken as to do operations
in such a way that kernel deadlocks and such are avoided. For
example, on Solaris you use ufs, however, you can't use logging ufs
because of known deadlock problems.
I'd assume that the use of ext2 on Linux is for a similar reason.

Fascinating. I did not know of UFS logging issue on the cache
partition.
Strangely, I haven't heard of any issues. does ext3 have this issue
as well?
I had used logging ufs as a cache partition for years without a
problem as well -- but in the past couple years ran into deadlocks. I
remember reliably seeing them under Solaris 10x86 on a Dell 2650 where
it'd lock up right after AFS started and some automated processes were
busy trying to access it.
