This isn't showing up in the troubleshooter for some reason so filing it manually. I'm seeing this denial on boot when systemd tries to create /dev/loop-control , and I think that causes anything that tries to use a loop device later on to fail: Jul 26 15:39:25 adam.localdomain systemd-tmpfiles[394]: Failed to create device node /dev/loop-control: Permission denied Jul 26 15:39:25 adam.localdomain kernel: type=1400 audit(1374878365.880:8): avc: denied { create } for pid=394 comm="systemd-tmpfile" name="loop-control" scontext=system_u:system_r:systemd_tmpfiles_t:s0 tcontext=system_u:object_r:loop_control_device_t:s0 tclass=chr_file Jul 26 15:39:26 adam.localdomain systemd-tmpfiles[529]: Failed to create device node /dev/loop-control: Permission denied
oh, sorry, forgot to mention, this is Rawhide: selinux-policy-3.12.1-66.fc20.noarch systemd-206-1.fc20.x86_64
Should be fixed in the latest build.
