wounded in the line of duty
You MUST be joking...
Ubuntu managing might be nice for 5-10 servers, but imagine having 500+ servers.
Do you want to log onto every box that needs updating and do a sudo apt-get update (of if you want everything bar a few packages updates having to specify exactly which packages to update)
Once you've worked with RedHat Satellite, you don't WANT to go back : At work my team runs around 600 servers. In RedHat we've got channels like this :
Normal patch routine : first wednesday we do all the test channels, week after all acc channels etc.
I just have to select a system group, select which patches/errata/updates I want to push (both default RedHat and our custom RPM's), select which targets I want to patch and select a scheduled time and forget about it. With a few clicks I've patched somewhere between 10 and 300 machines.
The registration stuff you find frustrating to us is a plus : the rhn daemon checks in every 5 minutes with satellite. Through satellite I can issue remote commands to multiple hosts, I can see which hosts might (still) have a nasty security issue, which hosts aren't checking in at all (and thus not getting patched) etc etc.
Now that RedHat has opened up the code to satellite I expect Novell and maybe Ubuntu to include it within a year, as this is VITAL to the bigger enterprises.
