Somewhere between 5c4624e and 5202883, systemd stopped loading supplementary groups when starting services as non-root users. This particularly creates problems for [email protected].

I suspect commit 4d885bd.

systemd version the issue has been seen with

v231-830-g52028838a1bc

Used distribution

Arch Linux

In case of bug report: Expected behaviour you didn't see

In all apps:

$ id
uid=1000(grawity) gid=1000(grawity) groups=1000(grawity),3(sys),4(adm),10(wheel),50(games),100(users),108(vboxusers),150(wireshark)

In case of bug report: Unexpected behaviour you saw

In gnome-terminal, which is launched via systemd --user:

$ id
uid=1000(grawity) gid=1000(grawity) groups=1000(grawity)

In case of bug report: Steps to reproduce the problem

unit=$(sudo systemd-run --uid=grawity id 2>&1 | sed "s/.* //")
output=$(sudo journalctl -b -u "$unit" -o cat | grep 'uid=')
[ "$output" == "$(id grawity)" ]
