[MM3-users] Re: Again, after systemupgrade the log file in /var/log/mailman was owned by list:list instead of mailman:mailman and starting failed for this reason [support request]

Here is the output:

grep var_dir /etc/mailman3/mailman.cfg

# can be as simple as $var_dir/history.py to put the file in the var directory. # be different from a FHS layout. Most paths are based off the var_dir, and var_dir: /var/lib/mailman3 queue_dir: $var_dir/queue list_data_dir: $var_dir/lists lock_dir: $var_dir/locks data_dir: $var_dir/data cache_dir: $var_dir/cache ext_dir: $var_dir/ext messages_dir: $var_dir/messages archive_dir: $var_dir/archives template_dir: $var_dir/templates root@mail:/var/log/mailman3#

Bingo! That may be the relict of a previous installation (at former times, without venv).

Shall I simply change

var_dir: /var/lib/mailman3

to

var_dir: /opt/mailman/web/logs

? Is a restart required?
