|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
command copies the disk image specified by
|
|
.Ar image
|
|
into the memory disk storage area in
|
|
.Ar kernel .
|
|
The file system present in
|
|
.Ar image
|
|
will typically be used by the kernel
|
|
as the root file system.
|
|
.Pp
|
|
To recognize kernel executable format, the
|
|
.Fl b
|
|
flag specifies BFD name of kernel.
|
|
.Pp
|
|
The
|
|
.Fl I
|
|
and
|
|
.Fl S
|
|
flags specify the symbol names of image and size of memory disk
|
|
drivers respectively.
|
|
.Pp
|
|
If the
|
|
.Fl s
|
|
flags is given,
|
|
.Nm
|
|
will write back the actual disk image size back into
|
|
.Ar kernel .
|
|
.Pp
|
|
If the
|
|
.Fl v
|
|
flag is given,
|
|
.Nm
|
|
will print out status information as
|
|
it is copying the image.
|
|
.Pp
|
|
If the
|
|
.Fl x
|
|
flag is given,
|
|
.Nm
|
|
will extract the disk image from
|
|
.Ar kernel
|
|
into the file
|
|
.Ar image .
|
|
This is the opposite of the default behavior.
