		Possible mismatch between current in-memory boolean
settings vs. permanent ones.

When trying to run a docker container on Rawhide, I am seeing this AVC.
The policy as audit2allow -w shows allows svirt_sandbox_file_t as an
entrypoint for svirt_lxc_net_t.

# sesearch -A -s svirt_lxc_net_t -t svirt_sandbox_file_t -c file -p
entrypoint
Found 1 semantic av rules:
   allow svirt_sandbox_domain file_type : file entrypoint ; 

But when I run try to start the container, docker blocks the access.  I
don't see any constraints that would block this, and don't think
NO_NEW_PRIV is enabled any way, and I don't think it would be involved
here. 

Any idea why SELinux is blocking the access?
