Well, aside from having different inode numbers, rgrep is /usr/bin/rgrep,
and grep is /bin/grep. The ln manpage says hard links cannot cross
filesystems, and on my box, that would be the case here, if it were a hard
link (POSIX doesn't have this restriction -- hmmm, wonder how that would
work?).

I do note that at rpmfind.net, the latest RH rgrep is for v6.2. That's
pretty old, so it might be that the "one exe to grep them all" approach is
a more recent development. However, that would imply that I should have an
rgrep directory entry, whether symbolic or not, in /bin. But grep has only
1 hard link (itself).
