vzctl stop effectively calls 'init 0'.  Now that /sbin/init is your
script, it unconditionally truncates the log file, and then calls
/sbin/init.orig again without arguments.

To get what you want you need a slightly more elaborate script,
something like the following (untested):

#!/bin/sh

# file must be there - create it if we're pid 1
[ $$ = 1 ] && echo >/var/log/init.log
export CONSOLE=/var/log/init.log
exec /sbin/init.org "$@"


That said, I do think we need to implement some sort of serial
console-like device for VEs.  We'll see what can be done here.
