NAME
mkfsconf, mknvrsafe, mkfsboot - build file server boot media
SYNOPSIS
disk/mkfsconfig < cfg > cfgpart
disk/mknvrsafe [ -c config ]
disk/mkfsboot [ -m mbr ][ -p pbs ][ -l loader ] /dev/sdnn
DESCRIPTION
These programs assist in setting up boot media for the file
server. Media prepared with these programs will be ready to
use once authentication information is entered at boot time.
Mknvrsafe prepares an nvram file which points to the file
server's config device. See fs(8) for device specifica-
tions.
The file server configuration block itself may be written
with mkfsconf. Care must be taken when placing this block on
disk, since the file server's block size is typically not a
divisor of the media block size.
Mkfsboot builds a bootable 386 image from configuration in
the current directory on the image /dev/sdnn. The file
fsconfig is the file server configuration and the directory
9fat contains at least the files loader, 9conffs, plan9.ini,
fs.nvr. The default MBR, PBS and boot loader are /386/mbr,
/386/pbs, /386/9load, respectively.
EXAMPLE
To prepare an nvram file given the file server configuration
file fsconfig,
# format properly without password
disk/mknvrsafe -c `{sed -n 's:^config (.*):\1:p' < fsconfig} |
dd -conv sync -of 9fat/fs.nvr
And to write the configuration block to the partition fscon-
fig,
# need to add Tconfig tag
grep -v '^config' fsconfig | disk/mkfsconfig |
dd -of $d/fsconfig -oseek $offset

BUGS
Mkfsconf should not assume a 8192 byte block or require out-
side help to align partitions properly. Only works for 386
machines.
