Description Aleksey Nogin 2004-04-17 11:16:42 EDT
Because the single-user shell in running as system_r, not as sysadm_r,
 many things (including su, sudo and mail) fail to work (avc messages
below). It seems that running an interactive shell as system_r is
wrong in the first place, and it should be sysadm_r instead.

Comment 1 Bill Nottingham 2004-10-11 15:18:07 EDT
This is a policy bug. Is this strict or targeted policy?
Comment 2 Bill Nottingham 2004-10-11 15:21:44 EDT
Also, does it still occur - this *looks* to be fixed in the current
strict policy.
Comment 3 Aleksey Nogin 2004-10-11 15:25:58 EDT

This was before the policy was split.

> Also, does it still occur

I am still running FC2, so I do not know.
Comment 4 Daniel Walsh 2004-10-12 09:53:03 EDT
I am marking this as fixed in Rawhide.
