There is https://github.com/systemd/systemd/issues/16896
It was closed wontfix.
Thanks a lot for the hint!
I had a look at the explanation and the corresponding commit, and I
understand that it is not possible to have support on a per-mount basis
for the ProtectProc setting if the running Linux kernel is older than
version 5.8. But I have also learned that the old behaviour of systemd
(before version 245) can be retained at least just by replacing
"ProtectProc=invisible" with "ProtectProc=default" in the systemd service
units in question (after copying these files to /etc/systemd/system/ of
course). Then systemd does not try to mount /proc with option
"hidepid=invisible" and, thus, there is also no error message in syslog
any longer.
Best regards,
