When I wanted to run 2 yggdrasil processes on the same machine, yggdrasil said: Admin socket /var/run/yggdrasil.sock already exists and is in use by another process, so I searched if there was a way to set a custom socket path on the page, but there was no info. I had to dig into the yggdrasil code to find it. Having that option listed on the page would be better.
