automount EFI system partition to /efi fails

[lists@xxxxxxxxxxxxxxxxx (Chris Murphy)]

https://www.freedesktop.org/wiki/Specifications/DiscoverablePartitionsSpec/
*The ESP used for the current boot is automatically mounted to /efi (or
/boot as fallback),*

systemd-238-7.fc28.1.x86_64

I've commented out the /boot/efi entry in /etc/fstab and reboot but the ESP
doesn't get mounted to /efi or /boot or /boot/efi.


Full journal with systemd.log_level=debug.

I get a couple of confusing items:

[    3.971099] f28h.local systemd-gpt-auto-generator[476]: /efi already
populated, ignoring.
[    4.102022] f28h.local audit[476]: AVC avc:  denied  { read } for
 pid=476 comm="systemd-gpt-aut" name="efi" dev="nvme0n1p9" ino=3999777
scontext=system_u:system_r:systemd_gpt_generator_t:s0
tcontext=unconfined_u:object_r:default_t:s0 tclass=dir permissive=0


It's definitely empty. But maybe it's due to the avc. chcon fails to set
the type to systemd_gpt_generator_t which itself gives me an avc.

And some additional repetitions but no avcs. So I'm not sure what the
problem is.
