Yes, when a file is loaded with mmap, "cp" to the file is a recipe for
disaster. You have to use 'mv' or 'install', so that the new version of the
file gets a different inode number.

That's precisely the reason why 'make install' uses the 'install' program
or an 'install-sh' script, rather than 'cp'.
