I like this. I like this a lot.

I can see this as being a major win in some circles. For example,
providing builds of packages for Solaris in its native packaging format
would virtually overnight be able to provide a larger package repository

I don't think I see it that way.
I expect that the number of Linux / Solaris users will increase as a
result, and that some will choose host package format, and that some
will choose pkgsrc format. And the incentive will be there for pkgsrc to
be able to offer something in its package management tools that isn't in
the "host" tools.

Do you expect to be able to fully handle the install scripts and all the
other current magic that pkgsrc does (creating users, etc), in SVR4
