Subject: Package installation - trouble specifying environment variable

Hello
Reading through the documentation, the cleanest (and changewise most confined)
way to enable non-interactive package installations in debian would be:
DEBIAN_FRONTEND=noninteractive /usr/bin/aptitude --assume-yes --quiet install
This way packages are installed without user interaction via cfengine, but if
apt-get is called from command line (or anywhere else), then the user is being
asked.
However cfengine doesn't like it if I tweak the std-library accordingly:
body package_method generic {
[...]
debian.have_aptitude::
package_add_command => "DEBIAN_FRONTEND='noninteractive' /usr/bin/aptitude
--assume-yes install";
package_list_update_command => "/usr/bin/aptitude update";
package_delete_command => "DEBIAN_FRONTEND='noninteractive' /usr/bin/aptitude
--assume-yes remove";
package_update_command => "DEBIAN_FRONTEND='noninteractive'
/usr/bin/aptitude --assume-yes install";
package_verify_command => "/usr/bin/aptitude show";
package_noverify_regex => "(State: not installed|E: Unable to locate package
.*)";
[...]
}
Scalar item in package_add_command => { DEBIAN_FRONTEND=noninteractive
/usr/bin/aptitude --assume-yes --quiet install } in rvalue is out of bounds
(value should match pattern "?((:\\.*)|(/.*))), near token
'DEBIAN_FRONTEND=noni'
[...]
Validation: Scalar item in package_add_command => {
DEBIAN_FRONTEND=noninteractive /usr/bin/aptitude --assume-yes --quiet install }
in rvalue is out of bounds (value should match pattern "?((:\\.*)|(/.*)))
a) How can I change the parser and make this a valid syntax?
or
b) How can I set an environment variable beforehand?
or
c) Are there any other options, except bruteforcing aptitude to always use a
noninteractive frontend (very unclean and disruptive) or writing a wrapper
script (another file to distribute and take care of).
Btw.: Why isn't this already part of the standard library?
