Fantastic, thanks for the link.  The comparison is icnomplete, however
it is stated that Reiser4 is good for small files and LOTS of them. 
Sounds like a good choice for squid cache.

I'm not running my linux boxes in a real multiuser environment yet, so
I haven't needed ACLs to date.  I thought I heard that ACLs were
moving along, but I don't know any current status info.

I think ACL support requires a 2.6 kernel.  ACL support is primitive
in 2.4 IIRC and I would suggest running a recent kernel if you're
going to be using ACLs.
