I got it working I had no such issues save the contact_groups (which i posted in that other thread BTW).
Now I need to find a perl-ish way to take everything out of the database and put it in that flat file.
Perhaps I should make a smal conversion script, and freshmeat it or something
There is nagios-db, which is delayed, cuz it takes info from the flat files and puts it in a DB I think. So maybe it wont really matter in the end. hmmm.
