While having a look at the list of services I have on my Devuan Beowulf, I saw a couple that called my attention:

groucho@devuan:~$ sudo service --status-all
[sudo] password for groucho: 
--- snip ---
 [ - ]  brightness
--- snip ---
 [ - ]  gdomap
--- snip ---
groucho@devuan:~$ 

Granted, they are not running.
I understand that brightness is for a laptop or portable and could be removed.

But what use is gdomap?

Thanks in advance.

Best,

A.
