Thanks. I thought this was important since I'm always paranoid about
security. I wanted to be sure I could have Mosaic (my choice of browsers)
always configured for Cicero and not accidentally compromise my system...

If you're not part of the ICE, you may still be ok. While it's true that
some packages (like emacs) care about where their binaries go, not all do.
It's easy to configure Cicero to use a different path if you want to have
packages go in a different directory. There's no good way to do it on an
individual package basis with Mosaic though.

Other than a simple check in the scripts, there's really nothing to
prevent you from running Cicero under another uid. If you just want a
personal copy of a package (and it doesn't mind not being in
/usr/local) you can certainly use Cicero to install it. I should probably
add an option to supress the uid check...

These are pretty good ideas. I will give some thought as to how Cicero
could be modified to add more support for different installation options.
I think we'll still be hosed if a package has compiled pathnames, though...


PS. Unless this discussion takes a 90 degree turn back into WWWland,
Please don't followup to the list. I gladly take questions (though maybe
the answer is "Cicero's not available yet" 8-)
