Bug 85404

Description of problem:
I changed my umask to 0026 some time ago. Yesterday I used network configuration
(providing the root password when asked) to change the phone number for a ppp
device and altered nothing else.

I have verified the following through controlled experiments.

After hitting Apply to commit the changes I got lots of errors which I tracked
down to the following files having access bits of rw-/r--/---, /etc/hosts,
/etc/resolv.conf and (possibly) /etc/aliases.db.

It appears there are two bugs:
my personal umask rather than root's is being used
unnecessary files are being updated

The end result of these two bugs is that I can render networking unusable for
non-root users (before you ask root's umask is the default 0022).

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Have a user set their umask to 0026
2. use the network config t change the phone no of a ppp connection
3. hit apply
4. ls -ltr /etc

Actual Results:  /etc/hosts, /etc/resolv.conf and (possibly) /etc/aliases.db
have access bits of rw-/r--/---

Expected Results:  these files should not have been altered, but if they were
the access bits should have been rw-/r--/r--
