I want to use your cache fs work for a research project I'm working on
(involving netbooting machines), was hoping that you could provide me w/ a

I've been following the development on linux-fsdevel, but am unsure where the
latest patches are stored (besides being posted to the list) and what kernel I
should apply them to.
Look on:
http://people.redhat.com/~dhowells/fscache/
http://people.redhat.com/~steved/fscache/
The patches should apply to the vanilla kernel.
To actually use it with NFS, you need to start the cache by mounting the
filesystem that's going to back the cache, then start the cache by running
cachefilesd (which is in FE6 and also on SteveD's pages) and then mounting NFS
with "-o fsc" - for which you'll need an updated mount (util-linux package) -
also available from SteveD's pages or FC6.
what file system is reccomended to be the fs-cache backing store? (ext2,
3....?)
seems that ext2 would be the most performant, but I could be wrong.
also from experience now on debian, one needs glibc 2.4 in order to
build cachefilesd as the *at() functions arne't in the 2.3 tree. the
2.3.999 is only available in experimental.
