Running commands on NixOS fails

[ianmjones]

When running streamdeckd on NixOS it looks like a command has been started as a PID is returned and no error shown, but the command does not actually start.

In the above screenshot streamdeckui has in theory been started by the Stream Deck via a button push, but it never shows up.

This is because streamdeckd uses something similar to /bin/sh -c '/usr/bin/nohup streamdeckui' to start the streamdeckui command. While NixOS has /bin/sh available for backwards compatibility, /usr/bin/nohup does not exist, but nohup is available on the PATH at a build dependent nix store path:

I expect nohup is going to be available on the default PATH for any Linux distro, and therefore I think it would be safe to call nohup without the /usr/bin/ prefix.

PR incoming! 😄
