[Spacewalk-list] Kickstart/DNS issue

[Mike Wilson]

I was able to get it to work with an IP address rather than the DNS name.
Still frustrating that DNS wouldn't work, even though I've checked and
checked, and the spacewalk server is in DNS and WILL resolve.

at Systems | Kickstart | Profiles | Kickstart Details | Advanced Options, I
changed the url option from

--url /var/distro-trees/CentOS5

to

--url http://10.xx.yy.zz/ks/dist/CentOS5/

That seemed to do the trick.
