11/3/71 MKFS (I)
NAME mkfs -- make file system
SYNOPSIS /etc/mkfs t
/etc/mkfs r
DESCRIPTION mkfs initializes either a DECtape (argument "t")
or an RK03 disk pack (argument "r") so that it
contains an empty file system. mkfs or its
equivalent must be used before a tape or pack can
be mounted as a file system.
In both cases the super-block, i-list, and free
list are initialized, and a root directory con-
taining entries for "." and ".." are created.
For RK03's the number of available blocks is
4872, for tapes 578.
This program is kept in /etc to avoid inadvertant
use and consequent destruction of information.
FILES /dev/tap0, /dev/rk0
