Rudder

Hi,

Regarding #7772 which was introduced by #7094, would it make sense to replace that env -0 or sed-magic to get the env. keys with something simpler, like this?

awk 'BEGIN { for (k in ENVIRON) { print k }; }'

The question is only, if awk is available on all systems that rudder-agent is supposed to work on (since you have rudder agent run's output piped through a pretty complex awk script, I presume "yes"?)
