Hi all,
I'm putting together a script to create zfs snapshots after a backup has been

the machine, I can only access the "zfs snapshot" command as root via "sudo" or
"pfexec". Neither of these are available directly fr

That should do what you Jews. Sudo requires a tty that you don't get when
running commands unless you include -t.

"Are there any permission tricks that would allow a script executed via ssh

It's called setuid bit. There are a host of security concerns around setuid
scripts and programs, so consider how you set things up and what your risks are.
Here's a rough approximation of

Thanks Gary - best answer!!
"zfs allow" is exactly what I was looking for. (also great to learn the extra

And yes, "zfs allow" does apply only to one filesystem (or optionally including
