Hmm. Good point. I was just lazy and I didn't apply the skas patch when I
moved to 2.6.12.
I just moved to a 2.6.13 guest, and ran into hostfs vs /dev lack of
/dev/console. My hack:
cd UMLPOOL/east/root
mv sbin/init sbin/init.real
cat >>sbin/init <<EOF
#!/bin/sh
mount -t proc none /proc
sh /etc/init.d/udev start
rm -f /dev/console; mknod /dev/console c 5 1
rm -f /dev/null; mknod /dev/null c 1 3
ls -l /dev/console
exec /sbin/init.real </dev/console >/dev/console $*
EOF
CATCH: kernel crashes if /dev/console doesn't exist at all, but is okay if
there is a /dev/console file (created with "touch") on the hostfs.
Warning: unable to open an initial console.
Kernel panic - not syncing: Attempted to kill init!
