Log:
test if usbmuxd can call statfs on /sys/fs/cgroup filesystem
Recent testing revealed that the usbmuxd service triggers SELinux
denials during its start, because SELinux prevents the usbmuxd
process from accessing the /sys/fs/cgroup filesystem. The TC is
able to reproduces the situation.
I believe this access should be allowed in SELinux policy. The TC
looks for appropriate policy rules.
The TC covers BZ#1936705.
