Put in /usr/share/initramfs-tools/ or /etc/initramfs-tools/.
+ With pull request #1476 (not yet merged) comes a verbose warning
  if /usr/bin/net doesn't exist or isn't executable. Just create
  a dummy...
+ If user haven't specified pool, but bootfs then use the first part
  of the bootfs path as pool name.
+ Add support for booting of a ZFS snapshot.
  Do this by cloning the snapshot into a dataset. If this dataset already
  exists, destroy it.
