The /etc/rc2.d (and 3, 4 etc) service files are numbered symlinks to
masters in /etc/init.d/. These are maintained by the chkconfig command
from comments at the start of each init script. You need to hack the
comment lines to stop chkconfig from rearranging stuff out from under
you.

BTW, if you modify the comments then RPM updates will probably not
update the init script, but make a .rpmnew file beside it; you should
diff them to ensure the new init script differs only in the comments
you have changed. Otherwise, move yours sideways, move the .rpmnew file
in, update the comment again.
