Same files in two packages - under which conditions is this allowed?

[Andreas Barth <aba@not.so.argh.org>]

Hi,

we sometimes have problems on upgrade that files were moved from one
package to another, and somebody forgot to set a "replaces" for this.

My question is now: Under which condition may package A in sarge
contain a file that another package B had in woody?

The following possibilities come to my mind:
1. A replaces B.
2. Some of the conflicts are ok. So, e.g. exim4-daemon-heavy has the
same file as postfix (/usr/sbin/sendmail), and that's not a problem.
But, are only versioned conflicts not enough? Or what requirements
does the conflict need to fullfil for this to work? Can somebody help
me here?



Cheers,
Andi
