Description of problem:

Using the perl API (for spacewalk 1.7), I can remove/add channels to a kickstart profile using kickstart.profile.setChildChannels.
However: using the webinterface, I see that, when I download the kickstart file, the old channels are still being used in the profile (the "repo --name" lines). Just pressing "Update kickstart" fixes it, but this seems very weird to me: shouldn't API kickstart changes in fact *change* the kickstart?

Version-Release number of selected component (if applicable):
1.7

How reproducible:
Always, see problem description

Actual results:
kickstart file still uses the old channels

Expected results:
kickstart file should use the new channels

Additional info:
I found that by removing /var/lib/rhn/kickstarts/wizard/<ks-label>-<orgid>.cfg prior to calling kickstart.profile.setChildChannels, the kickstart file gets regenerated properly. But this would mean I always need to be on the spacewalk server when changing channels via the API.
