Root user unable to change type

Hello,

I must be missing something in my understanding of selinux but I'm having
problem where the root user can not change the selinux type of a directory.
I am running in targeted mode.

I was experimenting and changed the type of /tmp/bah to "unconfined_t".   I
am now unable to either delete the directory or to change the type back to
"tmp_t "

chcon -R -t tmp_t /tmp/bah/

Results in:

chcon: failed to change context of `/tmp/bah/' to
`unconfined_u:object_r:tmp_t:s0': Permission denied

Audit2allow is suggesting "allow unconfined_t self:dir relabelfrom;"  but I
don't want to apply that because it seems that would allow all unconfined
files/processes to relabel themselves, is that correct?

Thanks for any tips.

Eric
