The
mdsetimage command copies the disk image specified by
image into the memory disk storage area in
kernel. The file system present in
image will typically be used by the kernel as the root file system.
To recognize kernel executable format, the
-b flag specifies BFD name of kernel.
If the
-s flags is given,
mdsetimage will write back the actual disk image size back into
kernel.
If the
-v flag is given,
mdsetimage will print out status information as it is copying the image.
If the
-x flag is given,
mdsetimage will extract the disk image from
kernel into the file
image. This is the opposite of the default behavior.
