NAME
installboot —
install a bootstrap on a
UFS disk
SYNOPSIS
/usr/mdec/installboot |
-n | -v
ufsboot bootxx
rawdev |
DESCRIPTION
installboot is used to install a "first-stage" boot
program into the boot area of a UFS disk partition, and initialize the table
of block numbers the
bootxx program uses to load the
second-stage boot program.
The options are as follows:
-
-
- -n
- Do not actually write anything on the disk.
-
-
- -v
- Be verbose, printing out the block numbers that
bootxx will use to load
ufsboot.
The arguments are:
-
-
- ufsboot
- the name of the second-stage boot program in the file
system where the first-stage boot program is to be installed.
-
-
- bootxx
- the name of the prototype file for the first stage boot
program.
-
-
- rawdev
- the name of the raw device in which the first-stage boot
program is to be installed. This should correspond to the block device on
which the file system containing ufsboot is
mounted.

init(8)
BUGS
installboot requires simultaneous access to the mounted file
system and the raw device, but that is not allowed with the kernel
securelevel
variable set to a value greater than zero
(the default), so
installboot only works in single-user mode
(or insecure mode - see
init(8)).
