Sorry, I confused myself. :-) Roots shell should be statically linked
if you are maintaining seperate / and /usr partitions...

No, this NG is not a helpdesk. I also fail to see what this has to
do with people in the "Linux world". Becuase someone makes a reply
that you deem "smart-ass" you paint "some people in the Linux world"
all with the same brush? You've got to be kidding, this NG is not
a help desk, it is meant to discuss Linux related things. If I or
anyone else chooses to help, it is because we care enough about Linux
to want to see people have a good experience with it, not because it
is mandated that we must help in a polically correct manner.

It would obviously be smart if you could make the 3-finger

'logout' in the inittab line work?

~~ Hi, there,

For both OS's:
tin, trn, slrn, pine, krn, Netscape, etc..
However, on Solaris I think only Netscape is available as part
of the default install. And that is only as of Solaris 8. Other
than that, you will need to get Solaris packages installed via
'pkgadd -d package', or compile them from source. Netscape
is installed with its own 'ns-install' script however. On Linux,
some or all of the above news-readers are installed by default,
on most dists.

Thanks for telling me. I always thought I was running Linux, but apparently it's
just Windows in disguise. I mean, how else would I be able to use my PCI modem
to post this message?

It seems, that my question was somehow not correct. I wanted to know
which BIOS functions are needed to _start_ Linux. I know that the kernel
itself doesn't need the BIOS anymore. So to ask again : which BIOS
functions are needed to start Linux.

Hey guys,
Wondering if some of you could possibly help me in my hour of need .... :)
I work at a school down under in Cairns, Queensland, Australia and need a
script to add hundereds of students to a Slackware 7.1 box I have just
installed and configured. I have searched the net considerably but can not
seem to find a suitable one. I did find one in Dutch called "usrmgr" but it
didn't do much for me.
Can someone please lead me in the right direction or email me one if you
have one on your server ...?
Thanks alot ... it's much appreciated.

It's unnecessary to "boot into single mode". When you are ready, just
change to singleuser runstate using 'init S' or 'telinit S'. When you
are done, you can switch back to multiuser or X runstate with the
proper init/telinit command. No reboots necessary

The Tips-HOWTO (question 2.6) suggests (generic):
(cd /source/directory && tar cf - . ) | (cd /dest/directory && tar
xvfp -)

No,
telinit 3
or
telinit 5
Reboot if you want to make sure that your startup scripts properly
mount the new /var partition, though.
Once you've confirmed everything works,
rm -rf /old_var_directory

I recently tried installing Storm 2000 (from a CDROM that came with a
magazine) on a machine with only 32 MB of RAM and a 1-gig HD. I also read
the informative review at the URL above. I substantially agree with the
reviewer's findings on many points - I found Storm's installer easy to use
and particularly liked the package selection device. The graphic display
of the installation of each package is reassuring if you aren't used to
how long this process takes. I never even found the printed instructions
until after I did the install, but I had no trouble figuring out what to
do.
The problems I had were: 1) Storm 2000 couldn't find a screen resolution
that would work for me. I have an oddball older monitor no other installer
has correctly recognized yet, so this is no surprise and I would not
consider it a shortcoming. I fixed it by hand.
2) Unfortunately, regardless of what they say, I found 32 MB insufficient
to run Gnome effectively. It was so unstable I gave up. If I were more
familiar with Debian I would have downscaled Storm until it worked for me,
and I may come back and do so when I have more time to play around since
the installer is so easy.
If your theoretical windows-migrant user is expecting success on limited
hardware, my experience suggests they may be disappointed. Go with more
memory and a nice big screen so you can see all the writing Gnome shows
you, and it should be fun.

Members of a department at our university have installed VMware on
their linux (and other unix) desktops. The use of outlook for (at
least) scheduling is required, but they also "want to do their job".
And this was their solution.
