32.Os
33.Sh NAME
34.Nm mdsetimage
35.Nd set kernel RAM disk image
36.Sh SYNOPSIS
37.Nm
38.Op Fl svx
39.Op Fl b Ar bfdname
40.Op Fl I Ar image_symbol
41.Op Fl S Ar size_symbol
42.Ar kernel
43.Ar image
44.Sh DESCRIPTION
45The
46.Nm
47command copies the disk image specified by
48.Ar image
49into the memory disk storage area in
50.Ar kernel .
51The file system present in
52.Ar image
53will typically be used by the kernel
54as the root file system.
55.Pp
56To recognize kernel executable format, the
57.Fl b
58flag specifies BFD name of kernel.
59.Pp
60The
61.Fl I
62and
63.Fl S
64flags specify the symbol names of image and size of memory disk
65drivers respectively.
66.Pp
67If the
68.Fl s
69flags is given,
70.Nm
71will write back the actual disk image size back into
72.Ar kernel .
73.Pp
74If the
75.Fl v
76flag is given,
77.Nm
78will print out status information as
79it is copying the image.
80.Pp
81If the
82.Fl x
83flag is given,
84.Nm
85will extract the disk image from
86.Ar kernel
87into the file
88.Ar image .
89This is the opposite of the default behavior.
