 * 	I knew that! The idea was simply that by unlinking the file
 * first, it would then be safe to write the new file contents (as you
 * would be sure to get a fresh inode). Applications using the original
 * file contents would have references to the original inode, and the
 * inode kept around until the applications closed the file.

You'd get the same effect by moving init to init.YYMMDDhhmm and creating
a new init.  If the new one doesn't work, you can move the old one back
-- assuming you can start with the old one.

A standalone version of "mv" might be nice to have. :-)

 * application by installing a new version - it seems that the executable
 * is used for swapping. I don't know if NetBSD has the same problem...
