Any update on gss/krb5 no_root_squash issue

The HOWTO mentions:

4.5 A known issue using NFS with kerberos
_________________________________________

Even if "no_root_squash" option is used, while exporting a filesystem at the server, root on the client gets a "Permission denied" error when creating files on the mount point.

This is because there is no proper mapping between root and the GSSAuthName.

And indeed, I continue to see this on Fedora 16. Are there any better workarounds for this now? Any hope of this getting fixed? I need to have root access to certain directories, mainly for backups.

Thanks!
