[nycbug-talk] "every bit as good as Linux"
Tue Sep 21 10:37:42 EDT 2004
Sunny, as usual, your right on the ball with this one, and as much as I
stick to my guns on a few sticky issues below, you've got me to
actually sit down and take a good look at the LSB.
For everyone on-list here, this is the project, and it's totally worth

That's precisely what I was looking for- a reason not to disregard LSB.
Now this doesn't sound like such a bad idea after all- but how does
LSB it differ from the Filesystem Hierarchy Standard (FHS)?
I found that url, btw, in the redhat man pages, hier(7) viewable here
The FreeBSD hier(7) has oodles of Posix mention:

This I did not read, and now I will go read it. I stand corrected, I
hope the author of that bloody article does too.

Well, I don't know that I can agree with that, I've seen some fairly
awful low-level decisions that were consciously working outside of
POSIX- some stuff having to do with socket handlers etc...

Well, I sortof see what you mean, but for production boxes, (and also
the boxes I use for my own fun), I really don't like ANY package
management system- not Ports or Packages, cvsup, even darwinports- I
prefer a minimal server OS, build apps cleanly and stock from source
Across the BSD's this works well, across Linuxes this does not.

Perhaps strongly stated, but not FUD. You know me man, I'm not a
religious *NIX user- I'm just stating some facts here,
Top of my head: man pages for things Like Apache on Mandrake- do they
say one bloody word about the Apache2 proxying Apache1.x to make their
'Enterprise Server'? Or RedHat, do the man pages say a word about the
fact that the adduser(8) program DOES NOT EXIST by default, and one
should be using redhat-config-users? That info is buried nicely on the
RedHat site- once one figures out what they're looking for. I'll stop
and just state that I have not experienced this level of trouble in
The precise man page I get when calling up adduser(8) man page on
(Trick question: does anyone notice another problem here, besides the
binary not existing?)
It's nothing personal against Linux, I mean clients of mine use it, (so
I do to), and I'd LOVE it all to be better. Perhaps in 20 years I'll
be saying the same thing about some other OS, and pointing to Linux as
a mature model- but right now, this is the way it is.

Ok- understandable- but again, no. I could dig through old client
notes for inconsistencies that bit me, but to be straight, it's all
esoteric stuff that is a problem when compiling from source. I've
found that loads of Linux packages take for granted one lib or another
that they package WITH a given ported app, and one thing gets built
thinking it exists, another finds it not to exist- again, a problem
I've never had in the same way on any BSD, compiling things from
source. I don't know what else to say here except I wail and gnash my
