# cat /lib/systemd/system/reboot.target
cat: /lib/systemd/system/reboot.target: Permission denied
# systemctl reboot
... it reboots
Should systemd be doing some sort of access check on reboot.target?

I don't think so. The access check is on systemd-reboot.service i believe.

Thanks for the pointer, I put in an auditallow rule and got the following when
user_t runs "systemctl reboot". It's doing the permission check on systemd-
logind.
Do you have any idea of where I should look for the cause of this?
type=USER_AVC msg=audit(1585309343.652:285): pid=1 uid=0 auid=4294967295
ses=4294967295 subj=system_u:system_r:init_t:s0 msg='avc: granted { start }
for auid=n/a uid=0 gid=0 path="/lib/systemd/system/reboot.target" cmdline="/
lib/systemd/systemd-logind" scontext=system_u:system_r:systemd_logind_t:s0
tcontext=system_u:object_r:power_unit_t:s0 tclass=service exe="/usr/lib/
