You can remove the old GLIB by typing:
rpm --nodeps -e glib
HOWEVER this will break a large amount of rpm dependancies (so, for example,
if you later want to do anything with rpm where a package requries
(whether directly or not) glib, you'll also have to use --nodeps.
If you want to keep the rpm database sane, then get hold of an updated
glib rpm - Redhat should have one available for download, if not then
ask them to.

Disable swap:
swapoff -a
then recreate your swap partitions using

Are you running utah-glx by any chance? I had constant space problems,

If you had the two home directories different, then which one is to

The two entries will have the same uid and hence Linux will only take
the first one when looking up stuff; so having two simply won't work.
If you really want emergency root access, make a copy of bash and place
it in your normal (user) home directory, make it owned by root, and a
group you belong to, and change the permissions to 4750 (I believe).
Of course, this won't need a password, so is slightly dangerous. You
could always write a program which checks a password :-)
(but then that's what su does)

I don't like interactive setup programs; they mean that installing multiple
computers involve babysitting them for ages (The Windows Problem).
If you do make use of interactivity, make sure that there is a standard
way that hard-core Linux users or Linux admins can install it
non-interactively. Standard packages (rpm, deb etc) would be nice, but
it is a pain to make many of them for all the different formats.
Documenting exactly what files it places where and what changes to
configuration files would suffice, so the admin could write his/her
own script which installs a whole machine automatically.

KDE is in C++. That's kind of major, isn't it? Most of the GNU stuff
is in C though. UNIX-like systems are based on lots of small components,
so C++ is not such an advantage. KDE's much larger, so C++ is helpful.
GTK is written in C, although bindings are available in C++. However,
it does used a very object-based paradigm.
If you can't program, learn C first, it is much easier than C++ (just
make sure that you keep good programming habits; goto is a command
you should NEVER use, unless you need to optimize AFTER you've written
it properly)

Agreed. The right-button and F1 idioms are good ones, as are button
bars on apps and scrollwheels on mice. Writing decent documentation
is a different skill to writing a decent GUI. I have yet to meet
anyone at all who was good at both in the same application.

It isn't that hard with something like Tcl/Tk, Perl/Tk or TkInter.
You just have to remember that users aren't necessarily going to work
through things the same way you do, that they want *both* mouse and
keyboard navigation, plenty of help and a chance to undo things where
possible (and a really hefty warning where you can't undo!)
If you're genuinely interested, try to read a copy of Alan Cooper's
_About Face_ (ISBN: 1-56884-322-4) which, for all its strong focus on
'Doze, is a really good book on GUI design.

It isn't dead yet. But I don't think it has a log-term future.
Is AIX being ported to new platforms? No.

Is the number of computers running AIX growing? No.
Is the number of computers running Linux growing? Yes.

No.
However, somebody does in fact know the path, since dlopen() needs
to find your module as well. So you can just pass the same "filename"
argument as a parameter to your module.

And there is the Debian popularity contest, an optional package that keeps

Damn, I'm still trying to decide if you're being sarcastic or not, Peter.
You're good!
I've seen that people run out of space on their /etc, and came close once
myself, so I wanted a real big partition.
Surely you know these multitudes of details are easy to miss when working
one's way into Linux? I simply assumed, based on all I knew (precious
little, but improving) that I could declare an /etc partition during
partitioning, make it nice and big, and the install would take it from
there. In fact, it seemed to work just fine till the initial reboot.
BTW, I also asked about Supermount and its failure to work under a lot of
Mandrake install setups. How about that one? And the hang apparently
caused by a modification of /fstab while trying to "fix" it? I put that
line in fstab often and successfully before supermount became available.
thanks for the help, fragmented or not-
