  Script is configurable enough to adapt for any component removal and inse=
rtion command. ZFS needs to send proper event (with pool name in question, =
instead of GEOM name, for example), and some commands should be added to co=
nfig file for "zfs" type of GEOM, but, I think, as ZFS has extensive userla=
nd library, zfsd solution could be better for ZFS.

  But anyway, I don't want to touch any ZFS sources, as they are very compl=
icated.

  But I open for suggestions from ZFS team, of course.
