EDUCATIONAL LINUX THREAD -NEW



I think this should be on a different thread if we're going to continue with it.

We can do the apps if you can do the cd.

This indeed very interesting to me...

For older machines, yes great...

For new machines I know that you can install Linux on a DOS partition - or I think
you can - using umsdos. Correct me if I'm wrong anyone. If you can get it all down
to a reasonable 150Meg then it'd be no bigger than your average windoze program.
Then boot it from the windows startup menu?

1) It'd be a very easy way for people to try Linux.
2) They could have there Linux programs (that we're all going to produce) running
on all machines easily.

Yes, when you want sound etc. etc. then it all takes RAM. But if you have a smaller
kernel.. smaller window manager.. I'm not sure. I had Linux running on a Cyrix 300
with 16Meg and it was slow to start apps. But when apps were running it wasn't so
bad. You could use Gimp OK on it. That was with KDE running as well and sometimes
with enlightenment. So 16 Meg probably aint all that bad - you can certainly live
with it.

You don't have to do this with old machines. You could get cheap new ones with the
cheapest components cyrix chips or low end celeron - no hd, no fd, 10Mbit ethernet
or just serial cables.

Making CDS is very easy. Yes you'd need a good installation program.

I think what people might need is different little distributions for different
things instead of those big generic jobs like Redhat. For instance, an old computer
installation/cheap computer installation, a print server installation. All with the
simplest possible installation interface. But then we get the problem of detecting
hardware etc. etc. The same probs. that the bigger distributions have right now.
