Yeah, systemd needs to be able to create directories.
I think the AVC is truncated in what is pasted here, but it's easy to recreate:
AVC avc: denied { create } for pid=1 comm="systemd" name="media" scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:mnt_t:s0 tclass=dir permissive=1

Description of problem: As root, unable to mount devices by using: systemd-mount /dev/sd# - prevented by SELinux. It works if you have created a directory and run: systemd-mount /dev/sd# /mnt/temp-mount but should make a temporary one in /run/media/system Version-Release number of selected component (if applicable): Fedora 27 How reproducible: Steps to Reproduce: 1. Plug in usb hard disk 2. systemd-mount /dev/sd# 3. Fails Actual results: Nov 18 16:22:46 tank audit[1]: AVC avc: denied { create } for pid=1 comm="systemd" name="media" scontext=system_u:system_r:i Nov 18 16:22:46 tank systemd[1]: Started File System Check on /dev/sdd.
