Ability to change favicon

[segaura]

Hallo.
In issue #132 it has been suggested to mount the favicon files using docker this way

volumes:
  - /absolute/host/path/my-icon-16x16.png:/var/www/localhost/heimdall/public/favicon-16x16.png
  - /absolute/host/path/my-icon-32x32.png:/var/www/localhost/heimdall/public/favicon-32x32.png
  - /absolute/host/path/my-icon-96x96.png:/var/www/localhost/heimdall/public/favicon-96x96.png
  - /absolute/host/path/my-icon.ico:/var/www/localhost/heimdall/public/favicon.ico

If I do this I get these messages in the log

[cont-init.d] 10-adduser: exited 0.
[cont-init.d] 20-config: executing...
[cont-init.d] 20-config: exited 0.

and apparently this lead to a permanent and complete malfunctioning with this log

In PackageManifest.php line 168:

  The /var/www/localhost/heimdall/bootstrap/cache directory must be present and writable.

For those who managed to change favicon though docker, did you do something different or something else?

Hi,
We achieved this by putting the logos in the heimdall volume, for example in /config/logos, with all the files named favicon-.png
Then, we created a script in /config/custom-cont-init.d/copy-logos.sh with the following content :

#!/bin/bash

cp /config/logos/* /var/www/localhost/heimdall/public/

FYI with the nginx change favicons are now located in /app/www/public/

I made a custom Heimdall favicon set for my organization, which I'd like to contribute. They're just green dots, nothing too fancy (since Heimdall is a "Start page" of sorts... "green means go" felt symbolic of that, and is easy for people to relate to, what with traffic lights having green meaning go).

These can simply be copied over the default files found in heimdall/public. Harder to do in a Docker container.

Here's another custom favicon set, this time with the Wireguard logo. Great for when accessing Heimdall through a Wireguard tunnel (and your buttons/launchers are leading to different IPs/URLs than they are within your LAN).
