How can I do a minimized installation of Linux that supports TCP/IP and
doesn't need more than 30 MB. Or where can I find info about doing such an
installation?
The HOWTO's I found on this subject resulted in installations of more than
30 MB. How can I reduce the needed space?
Thanks

Dear Browne,
I have left the Unix industry for a few years already. Now I am moving back
to Unix/Linux environment believing that this is the future. I did not
realised that there are so many changes being made to Linux and I am very
happy to be back. So now, I am picking up new terms and working on new
environment. If I have offended you, please ignore my posting.
Thank you

Seems like a PCI arbitration problem is the most likley.
BTW, a real-time rule of thumb is that you need 10X performace on the

Are both PCI64s on one internal bus?

When the parent process is killed, it sends a SIGUP to every child.
As there's no default handler for this signal, the child process kills itself.
In order to keep the child and not the parent, you'll have to handle this
signal.

No offense taken; it's just that your question doesn't directly admit
a useful answer; Gnome components are able to start themselves when
needed, so all you really need to do is to start some application you
consider useful, and it'll do what's needed to start up other pieces.

If you edit your .xinitrc file, you can specify a window manager, such as
fvwm or afterstep or whatever. I think what you want to do is start
"enlightenment" instead of fvwm, and you will get a gnome environment.

I do not understand how Gnome components workst. Someone suggest (which I
have not tried it out) using ~/.xinitrc. That is a good start for me. If I
remember correctly, Unix services are all initiated from command line one
after another. (It could be shell scripts). What I am trying to find is the
script to initiate the Gnome component services.

I'm currently developping a six legged robots. The robot has an on-board
conmputer and we want it to boot from a flash disk. We use Linux
Mandrake. After long hour of trial and error, we managed to boot from
the flash disk and have the prompt for a logging name.
The problem is that any user name we enter (even root!) gives a "login

Does anybody has an idea about this problem?

Well, it's more than a set of libraries and surely it's safe to assume
that the OP wants the gnome "desktop" started up. The command to put
into ~/.xinitrc is "gnome-session", I believe. This will start the
panel and mc, sprinkle icons around, fire up various daemons and
so on.

You shouldn't be mixing up glibc and the kernel. The kernel "tree"
(under /usr/src/linux-2.2.16) is not a good place to be compiling
the C library. /usr/src/glibc-2.2.2 would be sensible. Read the
INSTALL documentation (and think about what you want to specify
in the "--prefix=XXX" option to configure.

Gnome component services are controlled by something called "goad,"
the "Gnome Object Activation Directory." Services are preregistered
there, based on .gnorba files found in /etc/CORBA/servers.
If an application using the Gnome libraries requires a service, it
first looks to see if the ORBit name server is running. If not, it
starts it up. If it is running, the name server is queried about the
required service.
If the service _isn't_ running, goad looks to /etc/CORBA/servers to
see how to invoke the program, and then does so.
This happens on demand, when you run an application. It more or less
"boots itself," so there is no need to put anything into your
xsession file to get it started.
For instance, if I run Galeon, a GNOME-ized version of Mozilla, and
ask to download a file, it automatically, without my needing to do
anything, starts up GTM, the "Gnome Transfer Manager."
Similar things happen with KDE applications; they don't use CORBA for
interprocess communications, but rather a library called DCOP.
Additional services get spawned when needed.
I'm pretty sure this is not what you're used to; you're likely
accustomed to services having to be conspicuously started and stopped,
as happens with daemons managed using init. The "desktop systems"
manage their services in an event-driven manner that eliminates that
visible startup process.
I'll reiterate: If you have some _application_ you want to invoke from
the very beginning, feel free to do so, tossing it into .xsession or
xinitrc.
The most likely candidate is a program called "gnome-session," which
provides the service of recreating groupings of Gnome-based
applications. If you've got Galeon, gedit, Abiword, and Gnumeric all
running, this session, gnome-session can save that information, and
next time you start up X and run gnome-session, it'll pop up Galeon,
gedit, Abiword, and Gnumeric.
The second most likely candidate is that you might want to start the
Gnome "panel," which is an application launcher fairly much analagous
to the NeXTstep "dock" or the "MS Office" icon bar that sits along an
edge of the screen.
If you're sure you'd want to run a Gnome-based text editor, like
"gedit" or "glimmer," feel free.
If you like tossing up a system monitor, like gtop, go ahead.
Beyond that, I'd not worry about it. You don't need to directly start
up "gtm," or the name server, or esd (sound server), or any of the
other components. Invoke the applications that you want.
