While I was destroying some snapshots, I found this interesting / disturbing.
Why is the same destroy appearing twice, on different TTYs?
[16:11 r730-03 dvl ~/tmp] % w | grep air dvl pts/2 air01.startpoint.vpn.unixathome.org 1:04PM 2:18 sudo zfs destroy data01/snapshots/homeassistant-r730-01@autosnap_2024-10-19_22:15:08_frequently dvl pts/1 air01.startpoint.vpn.unixathome.org Fri11PM - w dvl pts/4 air01.startpoint.vpn.unixathome.org 4:11PM - sudo zfs destroy data01/snapshots/homeassistant-r730-01@autosnap_2024-10-19_22:15:08_frequently dvl pts/5 air01.startpoint.vpn.unixathome.org 1:07PM 33 -zsh (zsh)
What’s up with that? And why different times?
It is not always repeatable:

It’s repeatable, even within tmux:
