I have downloaded and installed in a Debian 9 environment.
There are a couple of differences that I have seen so far.
First, most importantly, the udev rules are in /etc/udev/rules.d.
Secondly, it appears that the journalctl command does not like the
output fields option.
I will install this on another machine that has a bit more device
activity, and comment later.
