HOME(8) System Manager's Manual HOME(8)
NAME
home, 40meg, 80meg, personalize, update, Disclabel - administration for local file systems
SYNOPSIS
gnot/home
gnot/personalize
gnot/update
magnum/home
magnum/personalize
magnum/update
pc/40meg
pc/80meg
pc/personalize
pc/update
nextstation/home
nextstation/update
DESCRIPTION
These programs help maintain a file system on a local disk for a private machine.
Home partitions a disk, copies the appropriate kernel to the disk, and makes a new file system on the disk. To do this, it overwrites the
vendor-supplied software on the disk with a copy of Plan 9. 40meg, 80meg, and 100meg configure disks and make file systems for disks of
the appropriate size.
Update copies the current kernel to the disk and updates files on the local file system. It only updates those files put there by the home
program.
Personalize removes the contents of the /usr directory on the local disk and copies a minimal set of files for the user who runs the com-
mand.
The file /rc/bin/nextstation/Disclabel, despite its name, is not an rc(1) script. It contains the second stage bootstrap program for
Nextstations booting from local disk. Before booting a Plan 9 Nextstation from disk, it should be installed in the partition
/dev/hd1label; this is normally done by nexstation/home.
FILES
/lib/proto/portproto
Mkfs prototype files for magnum/home, magnum/update, gnot/home, and gnot/update.
/lib/proto/386proto
Mkfs prototype files for pc/40meg, pc/80meg, and pc/update.
