I saw the latest update announcements on the announce list, so I ran "yum check-update" and did not see seamonkey in the list. Which I guess makes sense, since it's a name change from mozilla. However, devhelp is in the list, and "yum update devhelp" pulls in seamonkey as a dependency.
This seems like a sort of backdoor way to get seamonkey onto the system. Did these packages really come from the upstream this way? What if I had not had devhelp installed? Do I need to replace mozilla or not?
Aside to Dag: The galeon package from rpmforge has an version dependency on the specific mozilla package that's being replaced by seamonkey (rather than a greater-or-equal dependency), so it's not presently possible to install both seamonkey and galeon with yum.
