Why not use something like
I've just tested it on solaris, hpux, linux, aix, sco, irix, and it
worked fine on all those.
If you already have the PID in the filename, then I imagine this
renders filenames pretty unique, on the grounds that someone would
have to start an installation process, finish it, wait for the PIDs to
roll over, and start again within one second.
$RANDOM is, indeed, a pure bashism, and I'm inclined to say that if
you're going to try to fix a problem [name clashes], then you may as
well fix it properly.
