  FYI, under NetBSD, one can set the environment variable
RCMD_CMD to "ssh", and then mt/dump/rmt (which all use rcmd)
will use ssh rather than rsh.  Maybe someone could pull these
changes into FreeBSD?  So, the following works for me under NetBSD:
(backuphost has rshd/rcmd/rexecd/rlogind disabled)

setenv RCMD_CMD ssh
setenv TAPE backuphost:/dev/nrst0
(backuphost also needs to be in your .knownhosts file etc.)
mt status
dump <dump options> <filesystem>
mt status
mt offl

  I think this makes dump's job easier, as rmt passes status
and error messages etc. back and forth, right?

  Brian (looking forward to a time when the *BSD userland is more
unified than it is now...)
