In the Linux world it's quite easy to have live CDs, almost everything Linux comes as a live CD these days. Strangely, it's almost the opposite with BSD Unix. I dug the net and the mailing list archives and was not able to find any current, widely used, accepted, and respected live variant of any of the 3 major BSDs. A live system might come as a handy tool.

Even the NetBSD site does not link to it, does not mention it as at least being tolerated. I could use it without problem, nonetheless; just sayin'

Well - if you have a machine that is not even powerful enough to run
linux - say an old 386 that you found in a basement, you can run NetBSD
on it and start learning.

> I'd go for the second version as noted author of two BSD books (except for NetBSD), Michael Lucas also suggests a native install as well - and most importantly, I agree with him! He says virtualization might cause problems not present with software run natively, why even start with that, if you don't have to?

Jumping from zero knowledge to reading OS source code might not be the most effective 'introduction to C 101 course,' I guess.

Sorry about the assumptions - the BSD crowd used have an assumption
about code as literature. BSD C code is perhaps the most readable c code
around. ...Though plan9 code is similar. Back in the day reading a bit
of code was part of learning an OS. The BSD's have a long history so it
is sometimes easy to forget that it is not the 80's here. Wow, how
did i get to be 50.
