dpkginv
Query installed packages on Debian/Ubuntu-based systems and emit inventory as JSON
Usage
$ gem install dpkginv
$ dpkginv
If you want to include a per-host unique identifier to avoid relying
on FQDN, create a file /etc/dpkginv.conf containing:
system_id: <some_id_for_this_host>
You could, for example, set this to the value of
/sys/class/dmi/id/product_uuid or
/sys/hypervisor/uuid
Example
$ dpkginv
