permission?

[rollingblackout <thang@xxxxxxxxxxxxxx>]

Folks,

A fresh install from SGI XFS 1.0.1 gives:

[root@cafe /etc]# ls -lart|grep "\-rw-rw-rw-"
-rw-rw-rw-    1 root     root           66 Jul 20 09:05 shells
-rw-rw-rw-    1 root     root           85 Jul 20 09:10 modules.conf
-rw-rw-rw-    1 root     root           94 Jul 20 23:53 resolv.conf
-rw-rw-rw-    1 root     root          194 Jul 21 12:37 hosts

Are these considered "normal"?  Any other place where world writable?
Thanks,
