Do you have any examples of groups that the user should be in? Wondering if there should be any groups set by default.

adm - could be used to read logs in /var/logs
docker group could be used to read docker container logs.

Plus, sometimes apps write logs to custom location, limiting access to some custom user and group. (i.e. postgres:postgres)

Hello
I just found this MR wich was merged. Exactly what I need [adm, docker], but it looks like it was removed again partially: roles/alloy/tasks/install.yml#L16

I still see it as diff:
git diff 1e161d775b2e16e2a9eaa42aa988fcb6a1a51089 8dbd124a04d2d68689fa7fa3be91db3b077b7589 install.yml

But it was removed in latest change:

git diff 8dbd124a04d2d68689fa7fa3be91db3b077b7589 install.yml
