new ZFS installs completely broken in Wheezy/Sid

[Robert Millan <rmh@debian.org>]

My current summary:

1- kfreebsd-8 images can't currently be used to install *anything*
when zfsutils-udeb 8.3 is being used, i.e. when they fetch their
packages from sid.  It seems the default is still zfsutils-udeb 8.2
for debian-cd images (netinst, businesscard) but not for netboot.

2- kfreebsd-9 images can't currently be used to install Wheezy (which
is the default AFAICT), because:

    2.1- Last stage of the installer is unable to find
kfreebsd-image-9-amd64 package. Will be fixed when kfreebsd-9
migrates.

    2.2- zfsutils 8.2 in /target with a kfreebsd-9 runtime breaks
grub-install (even if zfsutils-udeb is 8.3). Will be fixed when
zfsutils 8.3 migrates.

    2.3- /boot/zfs/zpool.cache is NOT present!! No idea why this
happens, but potentially it could also break installed systems (since
they attempt to boot using outdated /boot/zfs/zpool.cache that was
generated with older ZFS version).  Could this be related to #651624 ?
