I agree with John on all counts here. Further, the idea of a
self-installing package, at least for the pkg stuff itself, addresses
the issue that someone else brought up about how to handle installation
of pkg by the installer for a new system.
For example it's pretty common in the Linux world to have a package
which is wrapped in a shell script which unpacks the tarball, verifies
it with a digital signature, then installs the bits from the tarball
where they need to go. Since pkg brings a lot of the pieces of this to
the party already, it wouldn't be hard to add the rest.
... and please feel free to insert your favorite version of my "We have
to get away from the idea that something is only good/cool/really part
of FreeBSD if it's in the base" rant here. :)
