.Sh DESCRIPTION
The
.Nm
utility installs and removes disk bootstrap software.
.Nm
can install
.Ar bootstrap
into
.Ar filesystem ,
or disable an existing bootstrap in
.Ar filesystem .
.Pp
(XXX: flesh out description of primary & secondary bootstrap, ...)
.Pp
The options recognized by
.Nm
are as follows:
.
.Bl -tag -width "foobar"
.
.It Fl b Ar bno
Install
.Ar bootstrap
at block number
.Ar bno
instead of the default location for the machine and file system type.
.
.It Fl c
Clear (remove) any existing bootstrap instead of installing one.
.
.It Fl m Ar machine
Use
.Ar machine
as the target machine type.
The default machine is determined from
.Xr uname 3
and then
.Ev MACHINE .
.Pp
The following machines are currently supported by
.Nm "" :
.Bd -ragged -offset indent
.Sy vax
.Ed
.
.
.It Fl n
Do not write to
.Ar filesystem .
.
.It Fl o Ar options
Machine specific
.Nm
options, comma separated.
.Pp
Supported options are (with the machines for they are valid in brackets):
.
.Bl -tag -offset indent -width append
.
.It Sy append
.Em [ pmax ,
.Em vax ]
Append
.Ar bootstrap
to the end of
.Ar filesystem ,
which much be a regular file in this case.
.
.It Sy sunsum
.Em [ pmax ,
.Em vax ]
Recalculate and restore the Sun and
.Nx Ns Tn /sparc
compatible checksum.
.Em Note : No The existing
.Nx Ns Tn /sparc
disklabel should use no more than 4 partitions.
.El
.
.It Fl t Ar fstype
Use
.Ar fstype
as the type of
.Ar filesystem .
The default operation is to attempt to auto-detect this setting.
.
.It Fl v
Verbose operation.
.El
.
.Sh ENVIRONMENT
.Nm
uses the following environment variables:
.
.Bl -tag -width "MACHINE"
.
.It Ev MACHINE
Default value for
.Ar machine ,
overriding the result from
.Xr uname 3 .
.
.El
.
.Sh FILES
XXX
.
.Sh SEE ALSO
.Xr uname 3 ,
.Xr boot 8 ,
.Xr disklabel 8 ,
.Xr init 8
.
.Sh HISTORY
The
.Nm
utility first appeared the depths of time (XXX).
This version appeared in
.Nx 1.6 .
