> ZFS is non-free so of course it cannot be part of Debian proper
ZFS is under the CDDL which is a perfectly good free and open-source software license, just some people view it as incompatible with GPL (IANAL, but this is apparently somewhat controversial; see the wikipedia page) so Debian doesn't distribute ZFS .ko files for Linux in binary form. They do, however, have an official package for it[1], just using DKMS to compile it locally.

If some people see it as incompatible, its not perfectly good then, is it.
