Not won't, *can't*.

If you want to remove the symlink, you need a compatibility symlink
in the other way.

At that point, you have 1) a package that moves its script from
/etc/rc.d/init.d -> /etc/init.d 2) a package that removes the
/etc/init.d symlink and replaces it with the directory. Watch
the RPM state machine....

1) Processing upgrade of package foo..
   /etc/init.d/foo <- new file in new path, will write
   /etc/rc.d/init.d/foo <- old file in old directory, will remove
2) Pre transaction:
   /etc/init.d symlink removed, /etc/rc.d/init.d directory moved to
   /etc/init.d. /etc/rc.d/init.d symlink created
3) Transaction is run
   /etc/init.d/foo is written
   /etc/rc.d/init.d/foo is removed
    - Oops, that follows the symlink and we remove the file we just wrote.
