pid_ns: Forgotten initialization of pid_max
Lesha's comment:
How it boots for you, folks, it remains a puzzle which I have no time
to solve. For me it crashes systemd right in in initrd. It is kind of
difficult to work without pids, is not it? :-)
We forgot to initialize pid_max for init_pid_ns which is static and does
not go through create_pid_namespace().
Previously systemd (ver 249) checked pid_max and if 0 is detected, wrote
TASK_MAX there.
In RHEL9 systemd does not try to be smart and just fails to work.
