[OpenIndiana-discuss] safely cleanup pkg cache?

[Stephan Althaus]

Hello!

The "-s" option does the minimal obvious remove of the corresponding 
snapshot:

$ beadm list

$ zfs list -t all -r rpool|grep "2020:11:03"
rpool/ROOT/openindiana-2020:11:03 42.1M  5.40G  36.4G  /
$ sudo beadm destroy -s openindiana-2020:11:03
Are you sure you want to destroy openindiana-2020:11:03?
This action cannot be undone (y/[n]): y
Destroyed successfully
$ zfs list -t all -r rpool|grep "2020:11:03"
$

Which facts am i missing here ?

Greetings,
Stephan
