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)).
