| Having a Common package format isn’t the best thing in the world. Just try using ximian and debian packages.
It works but you get dependency problems when the package names are not the same, or where a different dists pakage ‘A’ provide file x but Debain has file x in Package ‘B’ not it’s version of ‘A’
Then Package B from Debian will clash with package A from the other dist.
They alread have this problem with RPMs from RH, SUSE, etc you can use alien if I can [get|complie|bebotherd to complie] you own version from the source, thing are just as likly to work.
