Plan 9 from Bell Labs
There's an article in the most recent edition of Sysadmin magazine about Plan 9, which inspired me to get off my arse and actually take a look, something I've been meaning to do for ages.
The only sacrificial PC I have to install it on is my Libretto - sacrificial because despite me battling to get Linux on it, I haven't had enough time to get loads of stuff on there and start relying on it yet. Oh the joys of installing an OS with which I am not *at all* familiar on weird hardware.
I've got as far as getting the kernel to boot and load the initial boot disk image, using something similar to LOADLIN. But then kfs whines about "out of physical memory", so I suppose I need to add more. Bother.
