Can't say as I've run across many UNIX systems that don't have chroot.
You seem to be running 4.2BSD, so your system has it.  System V also has it.
It was introduced in Version 7, if I recall correctly.

Yes, you posted your program before.  And I posted mine before.  I claim
it's a lot easier to see that mine's more or less correct, as far as security,
since it depends only on chroot.  Also, mine not only extracts both the
UUCP and USENET maps, but (its main function) can be used to display them
to the user so that it is easy to discover information about a given host.
For example:

sally% uuhosts unmvax

Doubtless people can make up their own minds as to which program to use.
If there is any continuation of this discussion, let's move it to
net.sources.bugs (or direct mail).
