It has eliminated the Oops I reported earlier, which allows me to report
another. Here's the command sequence to reproduce (executed on boot,
from init):
===============================
insmod /boot/modules/fs/ramfs.o
mount -vnt devfs nodev /devfs
mount -vnt proc nodev /proc
mount -vnt ramfs nodev /tmp
insmod /boot/modules/block/floppy.o
mount -vnt minix /devfs/floppy/0 /floppy -o ro
tar -xzvf /floppy/boot/etc.tgz -C /tmp passwd
mount -vnt ramfs nodev /etc
cp /tmp/passwd /etc/passwd
tar -xzvf /floppy/boot/etc.tgz -C /etc
umount -v /floppy
umount -v /tmp
