>Summary
>    SELinux is preventing the nfs daemon from allow remote clients to write
>    local files.
>
>Detailed Description
>    SELinux has preventing the nfs daemon (nfsd) from writing files on the local
>    system. If you have not exported any file systems (rw), this could signals
>    an intrusion.
>
>Allowing Access
>    If you want to export writable file systems using nfs you need to turn on
>    the nfs_export_all_rw boolean: "setsebool -P nfs_export_all_rw=1".
>
>    The following command will allow this access:
>    setsebool -P nfs_export_all_rw=1
