Preserving a rev 0.0 ext2 filesystem

Hi Ted,

I'm still regularly using a Linux rev 0.0 ext2 filesystem as a ramdisk
on m68k, containing mid-90's binaries, from right after the a.out-to-ELF
transition, so I notice if someone breaks old syscall support.

Recently I wanted to change /dev/console on that ramdisk from a symlink
to chardev 5 0. Unfortunately I cannot mount it, without it being
upgraded automatically to a rev 1.0 ext2 filesystem. Apparently the
kernel has been doing that upgrade for ages.

Do you have a suggestion how to make that change, while preserving the
ext2 revision?

Thanks!

Gr{oetje,eeting}s,

Geert
