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.
