Public bug reported:
the zsys automatic zfs snapshots use up an incredible amount of disk
space by snapshotting things they shouldn't on every package install
(like user's home directories). as well, there seems to be no cleanup
done whatsoever. a month or so after installing my new desktop, my 1TB
SSD was down to ~9% disk space free. I ran `zsysctl service gc -a`, and
nothing changed. I manually deleted all automatic snapshots, and I was
back to 453 GB free.
I'm not sure what the intention of this behaviour is, but it doesn't
seem configurable, and it seems absolutely broken on the face of it.
Certainly unusable for any normal system usage.
Please correct zsys to have configurable snapshot settings, and have gc
do... something. anything.
