Description Lukas Slebodnik 2018-06-16 10:02:19 UTC
SELinux is preventing /usr/sbin/mount.nfs from map access on the file /usr/bin/umount.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that mount.nfs should be allowed map access on the umount file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'mount.nfs' --raw | audit2allow -M my-mountnfs
# semodule -i my-mountnfs.pp
