Description Kevin Arima 2003-09-08 23:09:58 EDT
Description of problem:
After starting install with linux askmethod, I had the text-mode setup get the 
IP information from the DHCP server.  I then went back and manually edited the 
gateway and the DNS server.  Regardless of what I did, it "remembered" the DHCP 
server IP address, and refused to change it.

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

How reproducible:
Once but repeatable

Steps to Reproduce:
1. Start install by using linux askmethod
2. Choose HTTP install
3. Obtain IP address from DHCP server
4. When asked to provide server and location, go back and attempt to change the 
DNS information manually.
Actual results:
Regardless of the changes to the DNS server IP, it "remembered" the old values.

Expected results:
Change the DNS information to what the user input.

Hmm, I have a fix to this, but it seems to cause name resolution afterwards to
fail.  Putting it here so that I don't forget what I tried.

Committed a slightly different fix to CVS
Comment 3 Jeremy Katz 2006-04-24 15:04:42 EDT
Mass-closing lots of old bugs which are in MODIFIED (and thus presumed to be
fixed).  If any of these are still a problem, please reopen or file a new bug
against the release which they're occurring in so they can be properly tracked.
