I see the main issue here as being the problem that different dependancy
trees on packages will make for major headaches unless pkgsrc stuff is
kept seperate enough to mitigate any problems, which has the potential
to reduce the benefits.
Firstly, how tightly will pkgsrc packages be installed into the host OS?
eg, can a native Solaris package rely on/use a pkgsrc-supplied Perl?
Or are you talking about maintaining pkgsrc packages independantly of
native ones but just use the same tools to install/update them? So,
continuing our previous example, would one need the native Perl and a
pkgsrc Perl to support native and pkgsrc packages?
In which case I can't see many benefits at all - I personally prefer
pkgsrc precisely because it doesn't interact with the OS package manager
yet is the same across all the supported platforms. For me, that's the
major attraction, but I can see it being useful to ease take-up on
non-NetBSD platforms ...
Would the intent be to provide binary pkgsrc packages for other OSes?
Would that impact on pkgsrc package builds?
