Of course all the things you mention are sys admin type issues, and as
I stated, such things do vary between different Unix variants and even
between Linux distributions. I stand by my statement that, from a user
perspective, Unix is pretty much Unix. I've had experience with Linux,
HP-UX, IRIX, SunOS, Solaris, DEC OSF, Paragon OSF, QNX, AIX, BSD and
probably some I've missed and never had any problem going from one to
the other as a user. As a sys admin some of them gave me HUGE
headaches they were so different, but not as a user. Still, learning
admin issues on a new variant was much easier once I learned my first
Unix system.
