i guess that those in need (assuming they exist) will find out and
complain and possibly we will move this code to a more appropriate
place. Where, i just have no idea.

In any case the dd hack is as much of a hack as the one in
write_mfs_in_kernel.c, and it is not bad at all:

    set `strings -at d kernel | grep "MFS Filesystem goes here"`
    mfs_ofs=$(($1 + 8192))
    dd if=${c_fs} ibs=8192 iseek=1 of=kernel obs=${mfs_ofs} \
	    oseek=1 conv=notrunc

	cheers
	luigi
