FreeBSD has FFS and UFS. UFS is FFS with ACL support. I'm still hoping
that NetBSD will keep the two filesystems separate. ACL is a good thing
if you need it, but a waste of space if you don't. And if you look at
Solaris man pages, the ACL support is very delicate when it comes to
sysadmins mistakenly doing things with chmod.
Also, Sun seems to allocate 1024 ACL entries per file. Check out
/usr/include/sys/fs on a Solaris box.
