Is there any specific location of "~:S:wait:/sbin/sulogin" in inittab

Issue

• Following line is added to the file /etc/inittab for applying root password to the single user mode:

~~:S:wait:/sbin/sulogin

• Is there a specific rule regarding the location of above line in /etc/inittab file?
• "~:S:wait:/sbin/sulogin" is written before or after rc.sysinit in /etc/inittab file?
