I also occasionally use OpenBSD, my preference of all the BSDs. It
should be noted they have contributed mightily to the *nix disporia.
Their reworked version of secure shell, OpenSSH, has become the defacto
standard used by almost all *nixes.

So -- in the legal sense, linux is not unix, in that it has no
history from AT&T's code. BSD is now also not unix, because it rewrote
all the code which was AT&T, so only the SysV systems are really still
unix, though they have absorbed many features of BSD.

Technically, you are correct. OTOH, Linux is so much like unix, anyone
truly comfortable with basic Linux would not feel out of place on a unix
box. I can see problems amongst ubuntu users, but users of, say,
Slackware or Gentoo would have few problems. I've pretty much tried all
the unix variants and settled on Slackware, it being the most unix-like
of the Linux distros, IMO.

Slackware was the first Linux distribution that I used, when I
switched from MS stuff back in 1993. I ran Linux 0.98 on a 4MB
'486 system and ca. 200MB of disk, with excellent reliability.
