rc directory

[Essy Ren]

I'll try install qmail to my computer,
and I follow the instruction from INSTALL guide 
the problem is I don't find the rc direktori at /var/qmail/
There's only 
/alias
/bin
/boot
/control
/doc
/man
/queue
/users
Why it's gonna happen ? and should I make the directory by myself ?
thanks ...
