Yes, listserv works in chroot environment.  Thanks to Valdis for your
encouraging words "implementable in theory".

The one problem I ran into was when I went into chroot and tried to start
listserv:

host# chroot /chroot-dir /bin/sh
# go

In "go" script, it tried to "su listserv -c ./go" (as I was running as root in
chroot), that's when it failed because it could not su to listserv.  The work
around it is to use "chrootuid":

host# chrootuid /chroot-dir listserv /bin/sh
$ go

And of course, you have to set up your chroot environment correctly.
