There are several package that need to be present in multiple versions
since they have different kernels they depend on. How can that work with
the current scheme?
Would it not be simpler to just allow installing multiple version of
the same package? The same is true for the libraries. F.e. we have two
dependency schemes for libc one through the major supplied in the name
libc5,libc6 and another in the version number. Unifying the dependencies
would simplify a lot of things.

No what I saying is that dpkg wont do
Depends: libc5 (>=5.4.17)
or
Depends: kernel (=2.0.27)
I am talking about the delta.

The same crops up in some of my packages and some easier solution would be
nice. With the current schem I cannot have for example one dosemu that
works for 2.0.x and another for 2.1.16 and later.
I would like to be able to do
dosemu (number one)
Depends: kernel (>=2.0.0) kernel (<<2.1.0)
dosemu (number two)
Depends: kernel (>=2.1.16)
And also for ibcs since it does not work under 2.1.X
Depends: kernel (<<2.1.0)
And for the bridge packages:
bridge (broken bridge support before 2.0.24!)
Depends: kernel (>=2.0.24), kernel (<<2.1.16)
bridgex
Depends: kernel (>=2.1.16)
