Dear Debian systemd maintainers, CC: Michael, This debian bug #903011 seems rather severe to me as this makes all the per-user resource control unusable as reported to the upstream at
https://github.com/systemd/systemd/issues/9502 https://github.com/systemd/systemd/issues/9512 https://github.com/systemd/systemd/issues/9578 and the upstream maintainers do not seem eager to address this bug, though the upstream report 9512 received "bug" and "v240 milestone" tags, while 9502 and 9578 keep "needs-reporter-feedback" tag despite sufficient feedbacks. There is a non-disruptive workaround for this bug, and it prevents all of the upstream bugs 9502, 9512 and 9578 above: (1) Make the following file as /lib/systemd/system/user-nonexistent.slice [Unit] Description=Dummy Slice for working around the bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=903011 Documentation=https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=903011 Before=systemd-user-sessions.service systemd-logind.service [Slice] Slice=user.slice [Install] WantedBy=multi-user.target (2) Run systemctl enable user-nonexistent.slice If the debian systemd maintainers (A) regard this group of three upstream bugs as severe, and (B) confirm that the above workaround works as expected and is non-disruptive, I would appreciate it if you consider incorporating the above workaround until the real cause is fixed in the upstream. Best regards, Ryutaroh Matsumoto
