A google search for "zfs" on my laptop (incognito mode) returns
wikipedia first, zfsonlinux as second entry, and open-zfs third.

I liked solaris for three things:
- zfs
- dtrace
- zones

however linux users now have zfsonlinux, perf, and lxc. Coupled with
the things linux already good at (e.g. up-to-date FOSS packages), it's
pretty much "bye solaris" for me :)

Most of the original zfs documentation (from oracle/sun) applies to
all zfs ports, including linux.
There's also http://zfsonlinux.org/docs.html (which has link to the
oracle docs).
The user list is also pretty much active (even more active than this list).

No, debian doesn't have a package for everything. It also doesn't
support everyting. Sometimes it's because of license issues, lack of
maintainer interest, or political/other issues. IIRC it was the last
one for zfsonlinux (package name clash/maintainer problems).

Use whatever you're most comfortable with. But don't dismiss things
just because you don't have enough knowledge about it.
