Description Thomas Köller 2023-07-22 17:56:37 UTC
Description of problem:
Attempted to mount local directory from remote via nfs.
SELinux is preventing rpc.mountd from 'search' accesses on the directory net.

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

If you believe that rpc.mountd should be allowed search access on the net 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:
# ausearch -c 'rpc.mountd' --raw | audit2allow -M my-rpcmountd
# semodule -X 300 -i my-rpcmountd.pp
