.Sh DESCRIPTION
|
||
|
|
.Nm 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
|
||
|
|
.Ar bootxx
|
||
|
|
program uses to load the second-stage boot program.
|
||
|
|
.Pp
|
||
|
|
The options are as follows:
|
||
|
|
.Bl -tag -width flag
|
||
|
|
.It Fl n
|
||
|
|
Do not actually write anything on the disk.
|
||
|
|
.It Fl v
|
||
|
|
Be verbose, printing out the block numbers that
|
||
|
|
.Ar bootxx
|
||
|
|
will use to load
|
||
|
|
.Ar ufsboot .
|
||
|
|
.El
|
||
|
|
.Pp
|
||
|
|
The arguments are:
|
||
|
|
.Bl -tag -width ufsboot
|
||
|
|
.It Ar ufsboot
|
||
|
|
the name of the second-stage boot program in the file system
|
||
|
|
where the first-stage boot program is to be installed.
|
||
|
|
.It Ar bootxx
|
||
|
|
the name of the prototype file for the first stage boot program.
|
||
|
|
.It Ar 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
|
||
|
|
.Ar ufsboot
|
||
|
|
is mounted.
|
||
|
|

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