Hmm... for rollbacks, all I do is tell zfs to roll back for me. Does this also happen with the zfs commandline? Rolling back mounted datasets could be problematic.

'sudo zfs rollback ' works.

Interesting... wonder what's broken there...

I checked it again. After the attempt, ZetaWatch freezed, blocking almost all keyboard until ended process in Task Manager. And I couldn't export pools or unmount drives until reboot macOS.

Now, I did rollback successfully (not updating ZetaWatch).
