+.Nd set kernel RAM disk image
+.Sh SYNOPSIS
+.Nm
+.Op Fl b Ar bfdname
+.Op Fl v
+.Ar kernel
+.Ar image
+.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
+If the
+.Fl v
+flag is given,
+.Nm
+will print out status information as
+it is copying the image.

+This version is intended for cross-building snapshots. It is not needed
