:SELinux is preventing /usr/bin/mount from 'mounton' accesses on the directory /proc/fs/nfsd.
:*****  Plugin catchall (100. confidence) suggests  ***************************
:If you believe that mount should be allowed mounton access on the nfsd directory 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:
:# grep mount /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 3 Daniel Walsh 2012-09-25 16:33:55 EDT
Is this mounting it a second time?

On my machine

ls -ldZ /proc/fs/nfsd/
dr-xr-xr-x. root root system_u:object_r:proc_t:s0      /proc/fs/nfsd/

>Is this mounting it a second time?
I do not understand.

>On my machine
[floki@localhost ~]$ ls -ldZ /proc/fs/nfsd/
drwxr-xr-x. root root system_u:object_r:nfsd_fs_t:s0   /proc/fs/nfsd/
[floki@localhost ~]$
Comment 5 Daniel Walsh 2012-09-25 16:55:53 EDT
mount | grep nfsd
Comment 6 Flóki Pálsson 2012-09-25 17:04:20 EDT
>mount | grep nfsd
[floki@localhost ~]$ mount | grep nfsd
sunrpc on /proc/fs/nfsd type nfsd (rw,relatime)
[floki@localhost ~]$
Comment 7 Daniel Walsh 2012-09-25 17:11:25 EDT
Which means it was already mounted.
