Right. But how much do I pay for Apache? How much do I pay for
postfix, sendmail, qmail, or exim? How about MySQL, or Postgresql? The
real issue, for me, is the version cycle. All of those packages have
minor updates fairly regularly, but none of them change major
functionality, and all of them provide packages to various linux
distributions, including Debian and Ubuntu. And most of them have
decent free support, at least via the sort of mailing list we're on now,
that includes those distribution packages. They may well tell you you
need to install the newest debian package, but they'll almost never tell
you that you have to recompile for basic functionality.
Again: this is a decision the development team made. It's not because
it's free, it's because they chose one particular mode of development.
I'm not saying it's wrong, necessarily, but it drives a lot of people --
like me -- to look for alternatives. Right now, the system pretty much
works, despite the fact that I'm using and older version
(2.4.7-6Ubuntu3). The problem, for me, is that if I write to this list
with a problem, I'll be told no one can help me unless I rebuild from
scratch. So far, it's been easier to work around problems or look for
help in the Ubuntu forums.
You're right that I don't need to keep rebuilding as new versions come
out, but that's only as long as I don't want to ask for help: if I need
to change how something works, or add functionality, even if it's
present in the version I have installed, I have to upgrade.
Anyway: this is really all pretty much irrelevant to the list as a
whole. I just wanted to make the point that this is an issue, and
perhaps something the devels should think about. If they decide to
continue on the way they have... well, that's their option. It's their
project, and they can do what they want with it. But they should at
least be aware that people are concerned about the current methods.
