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.
SEE ALSO
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)).
