This is a very good point. In looking into the $HOSTNAME variables on
systems I frequent, some of them use very long names or no $HOSTNAME (this
on one particular AIX box). In that case, I could use `hostname` or `uname
-h`.

But it's mostly an academic issue. I do very little admin work, so the
context (at work, at home, putty, X, etc) is almost always enough. When it
isn't, I put in a tag like "HOME", "LAPTOP", or "TEST" which I then ignore
while typing "rm -rf /". :-)
