SELinux is preventing mkdir from write access on the directory root.

[Lawrence E Graves]

SELinux is preventing mkdir from write access on the directory root.

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

If you believe that mkdir should be allowed write access on the root 
directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep mkdir /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
