Shellcommands - howto alter environment variables?

[Pieter Thysebaert]

Hello,

I'm using Debian Woody and use Fully Automatic Install to install some test 
machines.

I want to install proftpd on some of these machines, so the FAI-cfengine 
Shellcommands section contains something like

FTPSERVER::
     "DEBIAN_FRONTEND=noninteractive /usr/bin/apt-get --yes -f install 
proftpd"


However, this syntax is not accepted it seems (cfengine nags about wanting a 
full path-to-executable at the start of the command line)

How can I work around this to achieve my goal, which is to install proftpd 
without going into the debconf configuration dialog ?
