Matthias, I'm pretty sure that the v6 RL driver supports RL01s and RL02s,
the only difference is number of sectors on the RL01.

If you have an RL02 disk image mounted on /dev/rl0, and an empty
RL01-sized disk image mounted on /dev/rl1, you should be able to

	$ mkfs /dev/rl1 <size of RL01 in 512-byte blocks>
	$ mount /dev/rl1 /mnt

You can then copy over the root files from /dev/rl0 to /dev/rl1 with tar.

One thing to note, the RL02 kernel comes with swap at the end of the
RL02. You will need to rebuild a kernel so that the location and size of the
swap will fit onto a RL01 and still leave some file space. In fact, you must
remember to subtract the swap space size when you do the mkfs.

Best to do this on the emulator and get the RL01 image ready before
moving it to the /34. I also forgot to mention that you need to install
the bootstrap code onto the RL01 image. Check the mkfs man page for details.

Someone did say they have a program to do this. You might want to look
back through the mail archives on the PUPS web page.
