[vserver] exec export DEBIAN_FRONTEND=noninteractive

I'm processing /24 worth of vservers at a time via a noninteractive script,
and unfortunately can't make exec export DEBIAN_FRONTEND=noninteractive
stick. How are you doing it?

The script I use, called as e.g. ./modall.sh 1 254

#!/bin/sh
set -x
IPstart=$1
IPend=$2

function process () {
        vserver v${1} restart
        vserver v${1} exec apt-get update
        vserver v${1} exec export DEBIAN_FRONTEND=noninteractive
        vserver v${1} exec apt-get -y --force-yes install locales nginx postfix
        vserver v${1} hashify
}

for i in `seq $IPstart $IPend`;
do
        process $i
done

The error I'm getting is vcontext: execvp("export"): No such file or directory
Using just DEBIAN_FRONTEND=noninteractive is no good either, and there's
no way to execute multiple commands in one line with vserver exec

Do I have to build a script in each vserver and call it? If yes, can someone
post a recipe for that? Thanks.
