Contrast this with the 20 minutes it takes for my cable modem to download
and install the packages with other folks using ports system and it's really
inarguable as to what's better for package updating. With the constant CVS
updates I get from KDE, it's really kind of impossible to imagine this with
with a compile-only ports system. The frequency and size of the changes
make it nearly impossible for folks without a compile farm to update these
packages at that rate.

You still have a somewhat hackish dependency debugger in *BSD packaging
systems. You have portupgrade, which only kind of resolves these dependency
often leaving random stuff behind, while in contrast, I can full back out
dpkgs and reinstall them at will. It maintains a DB of files installed
in a package, permits file ownership querying, etc...

It's a phenomenal system.

Also, the quality of binary packages are rather unpolished. The way that
the FreeBSD deals with all of this is seems to be unpracticed, so you get
all of these funky things happening with dependencies. This is especially
the case if you rapidly "world" updates or do port upgrades often.  The
current schema is confused and difficult to work with regarding dependencies.
And I can't imagine it being scalable for rapid, high server load availablity
until these technical issues are solved so that package maintainers can
do the fundamental work instead of being distracted with side issues.

I think that's in principal a good idea, except that the *BSD packaging
system becomes highly strained with all of these rapid updates. It simply
hasn't handled this in the past well, was never design for these task,
antiquated and is super fragile. I can't imagine myself trusting a system
like that with changes to make or replace the current packaging system.
