[sabayon] Problem with Edgy Eft, LTSP and Sabayon

[André Geske <andre geske web de>]

Hi there!
I thought I might find someone in this mailinglist, who can give me some  
hints on how to use Sabayon without scrambling my LTSP config.
I'm running an Edubuntu LTSP server with 15 clients and up to 500 users  
who log in every week. Therefore I'd really LOVE to use a tool like  
sabayon.
But my first efforts under Dapper failed, so I uninstalled it and hoped  
for newer versions. In Edgy, I installeed it, created a default user  
profile and began changing some desktop settings / removing some  
application links when suddenly all of my ltsp users couldn't log in  
anymore.
Canceling Sabayon didn't help, aptitude remove sabayon didn't help, so I  
did aptitude purge sabayon and then the logins worked again.
As I don't know any alternative to sabayon (except manually creating a  
dummy user and copying all settings files to skel) I'm really willing to  
cope with some bugs here and there, but when my complete environment seems  
to stall after installation of sabayon, I get scared!

So does anyone have any ideas on what went wrong and how to prevent it  
next time?

I'm also not sure if the problem only occured because some users where  
logged in at the same time I was fiddling with sabayon. Should one make  
sure all users are logged off before using sabayon?

Also it's really hard to find any valuable information, howtos or  
tutorials for sabayon, at least for the new version included in Edgy.

So pleeeaase, if there's anybody who has a clue what I'm doing wrong, tell  
me! :)

Greetings,
Andre
