Syncthing is configure to run as root when installed via armbian-config

[PBRCW]

When syncthing is installed via arbiam-config the installation is made so that the service is run as root. This is discouraged by the syncthing team, see here:
https://forum.syncthing.net/t/running-syncthing-as-root/6316
So this should be default configured for the usage of an unpriviledged user.

Yes, this says it all.

Running as root is irresponsible and needs to be changed (checking id, using ${SUDO_USER} for the whole stuff and asking which user account to choose in case the user directly logged in as root)

Perhaps such implementation? https://github.com/armbian/config/blob/development/debian-config-submenu#L501-L521?

A part to create a new user/display error is missing.

[ThomasKaiser]

I would check if ${SUDO_USER} contains a valid user name. If that's the case this user will be used otherwise a dialog with available user accounts should be presented as you suggested. If there's none (only root) then I would stop and tell the user to create an unprivileged user account being member of sudo group first and then try again.

Service doesn't run as root, closing.
