Bug#648109: Impossible to use zfs as rootfs without creating a volume; should allow creating zfs filesystems (not just volumes)

Package: partman-zfs
Version: 14
Severity: important

Hi,

I just tried to install Debian/kFreeBSD using yesterday's netinst.iso from
http://cdimage.debian.org/cdimage/daily-builds/unstable/current/kfreebsd-amd64/iso-cd/debian-testing-kfreebsd-amd64-netinst.iso.

I had intended to use zfs as my rootfs, with the rpool itself being mounted
under / and perhaps /var, /usr and /tmp being separate zfs filesystems (not
volumes), so I could set different options on them.

There is apparently no way in the current installer to do this. The squeeze
installer allowed me to set a partition to "use as: zfs", and I could
specify a mountpoint.

Now, I can set it to "physical volume for zfs" and I can enter "configure
zfs" which allows me to create a pool. So far, so good - but there is no way
to specify the mountpoint for the pool, or to create filesystems (not
volumes) inside it.

Even switching to the 2nd console and setting up the mountpoints/filesystems
there doesn't help, because the partitioner doesn't realise /target has just
become a mountpoint and won't let the installation continue (it'd be nice if
there were a way to override that).

Justification for "important" severity: the bug makes the package almost
unusable (I'd say most people who want / on zfs don't need/want volumes).

Thanks and best regards,
