While trying out a custom SELinux policy for systemd, some denials
during system boot seem odd to me.
systemd pid 1 runs as systemd_t and has no execute_no_trans permissions.
The system runs in enforced mode, but systemd_t is currently a
permissive domain.
For debug purpose `auditallow systemd_t domain:process2 {
nnp_transition nosuid_transition };` is active.

Somehow the source context is systemd_t, while the pid is not 1 (and
the proctitle is not systemd).
Is maybe the context transition in the `nnp_transition` case delayed?

No. Not sure what it is that you are seeing. Maybe auditallow
execute_no_trans or double check that your policy isn't allowing it
(e.g. sesearch -A -s systemd_t -p execute_no_trans)

No execute_no_trans are logged (with an auditallow rule).
There is actually one execute_no_trans over itself (systemd_exec_t --
/usr/lib/systemd/systemd).
So systemd might re-exec or fork to get another pid.
But the pid in the denials is, in the case of systemd-logind, the
final pid of that daemon.
Also in the audit logs, the odd denial (e.g. 11/06/19 17:31:39.298:30)
is prior to the nnp_transition info (e.g. 11/06/19 17:31:39.466:35).

There is a "RuntimeDirectory=systemd/sessions systemd/seats systemd/users systemd/inhibit systemd/shutdown" in systemd-logind.service
That means that systemd will create /run/systemd/inhibit on behalf of systemd-logind

To: selinux
All-clear, nothing was wrong:
* systemd runs in pid 1
* to start a service systemd fork()'s
* child has same SELinux label but different pid
* systemd internally replaces the program name of the child, so the
proctitle is no longer 'systemd' but '(#name of service to start#)',
with these brackets
* after creating the environment, the child exec's into the service
daemon, thereby keeping the pid but changing the SELinux label and the
proctitle (brackets disappear)
