2.6 is what most distributions ship with. Besides working better with
desktop-type hardware, it allows device-name persistence for
hot-pluggable devices, hot-plug capabilities for PCI boards (PCI, PCI-X
and Compact PCI) which allows live repairs and newer ones offer
kdump/kexec functionality. Aside from that, it is actively developed and
*supported* by Linux distributors. There are a few problems, to be sure;
namely, the OOM-killer behaves badly and can cut off access to the box
entirely (bigger problem on overloaded servers) and the memory
oversubscription is a little flaky, leading to the OOM-Killer being
called. Both of these are tunable parameters, though, and
oversubscription can be turned off and OOM-killer can be made more sane
or shut off entirely. Additionally, the t3 driver (Tigon gigabit
ethernet driver) is fucking nuts and can cause stability problems in
kernel-space (I have seen one box freak out multiple times in a day when
under heavy network load using a NIC that is run by the t3 driver --
customer was very *NOT HAPPY* and we wound up disabling the t3 NIC and
adding an Intel PRO/1000 NIC board and all was happy).

Wow, I probably should have broken that into a couple of paragraphs.

I don't even know what OOM is and have no need for hotplugging. Had to use
kernel 2.4 for USB-storage (but DOS also supports that except for my SM card
reader). I probably would not take advantage of any features of 2.6 on my
1998-2001 hardware. Am giving people 2.2.26 and also optionally 2.4.31 on
computers with USB ports (two so far). 2.4 correctly identifies the amount
of memory even in computers with i810 video, where I have to subtract 1MB from
onboard memory with mem= to make 2.2 kernels boot. If I knew a whole lot more
I could try to write my own kernel without things I don't use. Some of our
computers have 12MB RAM so a smaller kernel is better.
I still can't get ssh working as 'user'.

Hot-plugging is useful for external devices, such as USB, Serial and
Firewire devices.
OOM means out-of-memory. The Linux kernel oversubscribes memory, and if
it runs out of total virtual memory (RAM + swap), it runs a daemon in
kernel space that forcibly kills processes and forcibly free()s their
memory so that the kernel will not panic. In some cases, it can behave
pathologically, but in many cases can keep the system up through a
transient memory shortages. On memory-constrained systems, a
well-behaved way of coping with OOM conditions is critical, and if the
kernel requests more memory and can't get it, it can panic or worse.

I don't run out of memory. We are giving everyone at least 64MB which is
plenty for running one browser. But I have had the problem on computers with
8MB or less RAM and no swap space - it just crashes.
USB storage works fine if you just load the drivers manually. Same for serial
devices.
Thanks for the explanations. I have never managed to use even 128MB RAM at
one time, as a single user.

Keesan, I regularly see boxes with 2 GBytes of RAM and 4 GBytes of swap
start shooting processes to free memory (and I usually get a ticket when
the OOM-killer shoots sshd or httpd). Real systems with real loads and
thousands of users accessing simultaneously a web application that talks
to a database require more RAM.
Manually loading drivers is an unacceptable inconvenience for many
users, and imposes a barrier to use. For most people, the operating
environment is simply a vehicle to use the commands that they need; most
people do not get off on faffing around with their operating environment
to achieve things that have been solved elegantly and reasonably.
P.S: My partner, who is sick and on medications responds "wake up and
come into the 1990s".

The computers we put together are for single users and don't run out of
memory. The one person who requested USB was really interested in learning
linux and had no objection to typing usb-on and mount /dev/sda1 /mnt.
And he was delighted with the 15 second boot. So while 2.6 may be much better
for your situation, 2.2 (2.4 if you need USB storage) works fine for mine.
Most of our computers and libc5 are from the late 90s already. A 1999 linux
runs faster on a 1998 computer than the latest and greatest.
To use the internet on the latest computer I set up, boot the computer,
type lin to boot from DOS to linux (or win for Windows instead), root
and Enter to login as root, dial to dial as root, login user and Enter to
login as user and automatically load X, then you can select programs from
the START menu with a mouse (or type their names in an rxvt). Type reboot
to reboot before shutting off the computer. I put little menus with
instructions along the way (in autoexec.bat and issue). How is this not
elegant?

this just gave me the idea of removing the gear stick from my car, after all
in town I hardly get to use anything other than the second gear, which with
a little getting used to you can also start moving with. that way the car will
be lighter and I'll have more space to move! less consumption and more
comfort! ;P

While you're at it, remove all of the seats and only install the ones
you need, adding and removing them as needed. And a car from 1982 drives
the same as one from 2004, so there is no point to buying anything newer
than 15 years old. Oh, and fuel injection annoys me, so anything I get
has to be carburated. If you ever need an oil change, Jim might be able
to help. He'll jack up the car, remove the drain plug, refill it with
oil, and let you drive off forgetting to reinstall the drain plug. When
your car dies, you can just pick up another junker from us for $50.

Good idea. Better yet, use a bike in town. Takes up much less space, makes
almost no noise or pollution, and is better for everyone's health.

And if you get hungry, eat some dried leaves and twigs and drink water from
the curb.

nope, we sure cant. It is part of what is in poop. I learned in my
biology class what else is in poop and I think I will be grossed out
for the rest of my life.

It tends to be yellow or brown in color, too.

The color is I think from broken down heme (from blood).

Re resp:141: Well, it's a bit like saying that driving a modern car is
more pleasant than driving a Model T. It's obviously true, to most
people, but there are still people who really enjoy restoring and
driving an antique.
Re resp:179: For what it's worth, I find 'gull' perfectly
acceptable. 'David' is awfully generic. ;)
Re resp:195: It also greatly increases your chances of getting killed
by being run over by a car, thus reducing the overpopulation
problem. ;)
