senmail, /etc/aliases.db ....

Running Rawhide, targeted/enforcing.

Notice this in /var/log/audit/audit.log:

type=AVC msg=audit(1188316403.485:16): avc:  denied  { create } for
pid=2704 comm="newaliases" name="aliases.db"

exe="/usr/sbin/sendmail.sendmail" subj=system_u:system_r:sendmail_t:s0

Looks like it is occurring when sendmail gets started during boot.

Running /usr/bin/newalises manually at root console works with no
AVCs, but leaves /etc/aliases.db with the 'wrong' label:

[root at localhost ~]# ls -Zl /etc/alia*
-rw-r--r-- 1 system_u:object_r:etc_aliases_t  root root   1512
2005-04-25 09:48 /etc/aliases
-rw-r----- 1 system_u:object_r:etc_t          root smmsp 12288
2007-08-28 10:27 /etc/aliases.db
[root at localhost ~]# restorecon -v /etc/alias*
restorecon reset /etc/aliases.db context
system_u:object_r:etc_t:s0->system_u:object_r:etc_aliases_t:s0
[root at localhost ~]#

Should /etc/init.d/sendmail fix the label after running newalises?
