Yes, however I'm afraid that if it creates a single disklist
for a glob, for instance /export/home/a*, creates snapshot /export/home
which I think would be acceptable.
But 'attempts' to create the same snapshot for glob /export/home/b*
and /export/home/c* those # zfs create snapshots will fail, which
may not actually be a problem.
However, when any of those globs completes and attempts to remove
the snapshot -- what will happen to the remaining dumps. They will
all lose their snapshots! (I think.)
I was hoping to have a snapshot for each of the directories within
the glob /export/home/a* which will work (on my system) since each
of the user directories is itself a mount point.
I recognize that there is no way to snapshot all of the As and then
all of the Bs.
I don't think there is a mechanism to maintain 'the' snapshot
until all of the globs complete. There is no cross-glob coordination.

The disklist posted differs only in that for the -A glob we ran with
zfs-snapshot rather than user-tar.
thank you,
