Hello. Accidentally I've found that installing a new world makes a
backup copy of init(8). See below:

> ls -lo /sbin/ini*
-r-x------  1 root  wheel  schg 482036 Sep 16 17:10 /sbin/init
-r-x------  1 root  wheel  -    482036 Sep 11 15:28 /sbin/init.bak

The /usr/src/sbin/init/Makefile have following line:

INSTALLFLAGS=-fschg -b -B.bak

What is the reason one should have /sbin/init.bak after installation of
a new world? Why the 'schg' flag is removed on this file?
