DEC suggests, actually, that I use *67* meg for swap on their workstations running X. Unfortunately, they shipped our machines with a single 104-meg drive, not enough for their operating system alone. We had to jump up and down just to get 208 meg drives to hold the OS and some other niceties. And I *work* there. This does not mean that this is _A Good Thing_. I can run V7 on a PDP with a single RL02 - about 10 meg. I don't mind V7, it's rather nice after SYS V and BSD monsters. >>80 Meg is nicer. > >That's about minimally acceptible for a system that's actually going to be >used. > Oh, come on. Mark Williams Co. sells a UNIX clone called "Coherent". It has a 64K kernel. They recommend 10 meg of disk. I don't believe it'll be too useful in 10 meg, but I plan to put it on my dad's laptop with 40. UNIX is beautiful because it's SMALL. I should NOT have to pay 1/2 the cost of the machine for disk to run the OS. Shared libraries are a step in the right direction, as are streams, but a SunOS kernel has those and is 600K - I suppose V.4 comes in around there somewhere. What is the world coming to?

Swap doesn't count, and neither does X windows or applications for this purpose, but today's UNIXes take up far too much disk space for just the heart of the system. Where's a AMIX system come in with and without the manuals? I bet it's about 30 meg or so without, and 40 with? Am I way too high? I hope so. Am I way too low? Please, I hope not. I had hoped Commodore, who could fit most of the functionality of UNIX into AmigaDOS, could squeeze the beast down to size some. But That's nto really fair, I suppose. >>Older versions have been quite frugal. I remember a PC/XT with a 20 Meg under >>Xenix Version 7...

And using or managing a large, ponderous system like UNIX could well become is unpleasant. UNIX is called UNix because it is MULTics made simple. I wish it had stayed that way. I don't fault Commodore for offering UNIX - I applaud them, I like UNIX, even its oversized modern incarnations. I just wih they could have cut it down to size a bit. And the reason that people still use UNIX when they're cramped for space or are only doing a bit of wordprocessing is because enough of its original personality remains to make it fun to use. >>Peter da Silva. `-_-' >>. > > >-- >Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" > {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy > "I have been given the freedom to do as I see fit" -REM ******************************************************************************* *Thor Simon * Okay, just a little pin-prick...There'll be no more-* *lancelot@spock.UUCP * Aieeeeaaaugh!-but you may feel a little _sick_. * *uunet!hsi!yale!lancelot* ---Pink Floyd *
