Modify GUI Theme

I have been trying to find out how to modify the visual theme of Nethserver. I am not lazy maybe just a bit dumb. I have been looking through the documentation and the forum. No luck.

I am very impressed with NethServer… I want to be able to modify the “NethServer 7.9.2009” displayed on the right top of the GUI so that I can tack on " - devlab" for one computer and " - Production" on the other computer. This way I can have both instances open on my monitor side by side and visually distinguish which instance I was modifying.

I would be grateful for any help.


Here is a guide for cockpit custom branding.

Haven’t tried but should be related to variables on /etc/os-release as stated in cockpit’s branding guide.
