AFAIK, you can't dd a directory only a file (block special files like
/dev/sda2 qualify here)
The "Right Thing" is to read the bootfloppy HOWTO and build something
up with either LILO or loadlin.
The quick and dirty thing is to dump a raw kernel to disk then use
"rdev" to set where that kernel looks for the root partition. For
example my machine mounts root from /dev/sda1, if I want to take my
kernel and boot a machine with root on /dev/hda1:
dd if=/boot/vmlinuz of=/dev/fd0
rdev /dev/fd0 /dev/hda1
you can set other various and sundry things with rdev as well
[EMAIL PROTECTED] jon]$ rdev -help
usage: rdev [ -rsv ] [ -o OFFSET ] [ IMAGE [ VALUE [ OFFSET ] ] ]
rdev /dev/fd0 (or rdev /linux, etc.) displays the current ROOT
device
rdev /dev/fd0 /dev/hda2 sets ROOT to /dev/hda2
rdev -R /dev/fd0 1 set the ROOTFLAGS (readonly status)
rdev -s /dev/fd0 /dev/hda2 set the SWAP device
rdev -r /dev/fd0 627 set the RAMDISK size
rdev -v /dev/fd0 1 set the bootup VIDEOMODE
rdev -o N ... use the byte offset N
rootflags ... same as rdev -R
swapdev ... same as rdev -s
ramsize ... same as rdev -r
vidmode ... same as rdev -v
Note: video modes are: -3=Ask, -2=Extended, -1=NormalVga, 1=key1,
2=key2,...
use -R 1 to mount root readonly, -R 0 for read/write.
The beauty of a LILO set up is that you can pass these (and other)
kernel params at boot time, which you cannot do with a raw disk.
