Both tar and cpio need rsh; they both have nearly exactly the same
(Though it seems odd that tar searches only for /usr/bin/rsh whereas
cpio searches for that and then /usr/ucb/rsh, /usr/bin/remsh,
/usr/bsd/rsh, and /usr/bin/nsh. Also, tar's rtapelib.c doesn't have
an RCS ident string.)
I should point out that using the library rcmd() functions rather
than using an external rsh is not necessarially a virtue; I've
replaced rsh with ssh on my systems so that I can use tar and cpio
via rmt securely. Because dump and restore don't call the external
replacement, I can't use them securely (or remotely at all--I've
disabled rexecd on my systems).
