It is those kinds of differences that make Debian superior to RH
(or so I've read ;) ).

Programs that hard code file locations are poorly written <period>.
OSS programs that do so will be replaced by versions that do not.
Non-OSS programs that do that will not be widely accepted in the Linux
world because they cause too many problems.
This is just one more issue I see as self regulating.
Remember, this is the UNIX world, not the MS "one" world (although
you'd never know it by looking at some of the programs out there).

This is a problem, environment variables are the solution.
A program that is so closely tied to another that it needs to parse the
config files itself will probably have synchronous releases (and perhaps
even close coordination between them). Dpkg is a special case, either
it needs to know the gory details about every package installable, or
leave the config stuff up to the program it is installing (which is what
it does).
Trying to force programmers to use a specific format for config files
will not work, identifying what needs to be exported so that the
software can coexist with other tools on the system will.
The real problem is not the multitude of config methods and file formats
around, it is a lack of understanding on the programmers part with
respect to the UNIX philosophy.

This is not an issue because a properly written UNIX/Linux program will
fit into any UNIX/Linux system with only minor tweaking.

Nothing, unless you think that your way is better than the other ways.

If OSS goes mainstream it will be because the commercial world CEO's see
an advantage to doing so, the programmers will have little choice in the
matter.

Instead of making money off the software, they will make money off the
manuals that go with it. It is really just an extension of one of the
solutions to the pirated software problem that existed in the early and
mid-80's. Think about it... what is more important, the code that can
be reproduced for next to nothing, or the knowledge of how to make use
of the code. If I was doing such a project I would give away the
program and charge for the documentation and online help.

Hmmm, I think you missed the point...
Why are they even looking at RH when MS does what they want (wrt apps)?

You can take the default RH packages and install them on Debian, then
they will both have the same "look-n-feel"... if that is the only
difference between the two distributions then what is the point of
choosing between RH and Debian (aside from the philosophical).
I think we have covered just about everything, so I am going to
summarize why I don't think we (the Linux community) need to worry
about RH becoming the MS of the Linux world.
RH is a Linux system and Linux (being a UNIX work-alike) has mechanisms
and standards that ensure compatibility between its different flavours.
If RH was to break with the UNIX/Linux way of doing thing they would end
up annoying their users, who have probably switched to Linux because
they see an advantage to the UNIX/Linux way. There is the possibility
that greed takes over and RH tries to dictate how things should be, but
this is precisely the major complaint I have heard about MS, and I find
it unlikely that RH will make that same mistake. Technically there is
not much RH could do to squeeze out other Linux distributions, they
could force other distributions to either adopt their way or jump
through a bunch of hoops so that users of the other distributions can
run RH developed applications... this is really no different than the
current situation where most applications are developed without a
specific distribution in mind. So, if RH does manage to become the
defacto standard of the Linux world, it will probably be because they
have worked harder in the marketing arena than the other distributions.
Later,
Bruce
