RHEL 5 SELinux and NFS

I just installed RHEL 5 in a server configuration. I now want to apply NFS to the filesystems. However, when I applied NFS I now get an SELinux error message about the use of portmapper as follows:

SELinux is preventing /sbin/portmap (portmap_t) "read" access to inotify (inotifyfs_t).

As part of the message it does provide me with the command line syntax to disable SELinux security for NFS. For me that is not the answer. I want to create the appropriate policy to allow NFS to work properly within the SELinux model.

I've been reading since last night about how to create an SELinux policy. It's been very tough to understand how things work as well as how to create a SELinux security policy.

Does anyone have any experience using SELinux they'd like to share. Where can I go to find out more information about how to create an SELinux Policy?

I'm finding it very tough to understand things so far, but I'll keep trying.

Adding SELinux policy for simple things changed a lot (got a lot easier) between RHEL4 and RHEL5, so the RHEL4 guide might not be very helpful. Try this:

If you're still having trouble after looking at that, post your actual AVC denials (probably in /var/log/audit/audit.log) and I'll walk you through it.
