INSTALLBOOT(8)      NetBSD/mvme68k System Manager's Manual      INSTALLBOOT(8)


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.

     disklabel(8), 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 vari-
     able set to a value greater than zero (the default), so installboot only
     works in single-user mode (or insecure mode - see init(8)).
