They very on the technique.

They do that as well. The RAM drive where The LiveCD allows the user to make temporary changes, add & remove programs to the temporary filesystem.

No hard drive is required. Only sufficient RAM. > if Ubuntu can run from a DVD, DOS certainly should also be able. Can DOS even run directly on a CD/DVD?

As you know, CD & DVD are readonly media and many DOS programs frequently use the program directory for caching and other data storage. Sure there are lots of programs that don’t store any data. But, many do. Running those on a read only filesystem will have unpredictable results at best. Simply setting TEMP=RAMDRIVE won’t cut it. > > and see the beauty of a GUI on DOS. > > the current 'LiveCD' is none of this. It sure does. However, at present only some packages are live at boot. Others can be installed by the user into the temporary filesystem using FDNPKG, FDIMPLES or whatever after boot time. I don’t think making every package Live by default is practical. It would be time consuming for Type-1. I don’t think it would be possible for Type-2 without moving to DVD. There is roughly 550MB of compressed packages on the CDs. Also, uncompressing everything would require much more RAM. Should DOS require 1 or 2 GB of RAM just to use a LiveCD? For RC1, I just picked most of BASE + some of ALL and a very few extras. I agree that maybe a couple games and maybe a GUI should be made Live by default. But personally, I don’t care which ones. Jim will decide what packages are Live for RC2 and Final. But if you have any specific suggestions or recommendations on which ones you would like to see, please do say. > > whatever the purpose of this 'LiveCD' imitation is, I probably just > don't get it. Wow. Did you try either? Maybe it’s me. But, I see no deviation in your quoted definition of a LiveCD and the two LiveCDs for 1.3-RC1. There are other possible ways to do a LiveCD. For example... If we had a driver that could directly use CD/DVD media like a hard drive and cache changes to RAM, then things could be different and possibly even better. But we don’t. I have far to many things on my plate to write one.
