Hi Dan,
Now we are able to remove unconfined types and users successfully. But after this removal we see a whole bunch of new denials related to initrc_t as follows
#============= initrc_t ============== #!!!!

Is this expected .. Is there an easy way to address these denials other than writing individual policies for the allow rules

Hi Dan,
I have a couple of more follow up questions.
- What we have seen on our systems is just running restorecon -R does
not fix the issue. We need to run restore -R -F to force the pick of file contexts. So it seems that the -F options does more things that just -R. Is that a correct understanding.
Yes -F will fix the User/role/mls fields as well as the type field, without the -F, restorecon only fixes the type field.
- After removing the unconfined types and users and doing restorecon
we see that root still is mapped to unconfined_u
root unconfined_u s0-s0:c0.c1023
Do we need to change this mapping as well. And if we do would it have any adverse effect on the system..
No this should be changed to sysadm_u. Which will cause your root account to login as sysadm_t.
You might have to turn on a couple of booleans to allow sysadm_t to login directly
ssh_sysadm_login --> off xdm_sysadm_login --> off

But some file security contexts still have unconfined_u

What would be the reason for that?
Thanks, Anamitra

If you have any processes running on your system that are unconfined_t then they will become unlabled_t and start generating AVC's. Any confined apps that are trying to read unlabeled_u files will start to fail also.
It is probably best to do this at Single User mode/permissive and then cleanup the disk.
