It looks like a good idea. I am also wondering if we should provide ZFS
support in our kernels. I have played a bit with it recently and its
clearly a killer feature. Currently it is disabled because we have
enabled ext2 support. Both have incompatible licenses (GPL v2 vs CDDL),
so that would mean disabling ext2 support. Any comments?

That's clearly something we need. BTW, do you know if the futexes
support in the FreeBSD 7.1 will be correct enough to use an NPTL glibc?
