Description

Maintainer: @wfleurant
Environment: ARM64

Description:
If possible, it would be nice to do the equivalent of ExecReload=/bin/kill -HUP $MAINPID when reload is run, instead of doing restart, which does stop and then start, which will remove the tun interface and destroy any modifications made to the interface. This will bring it into line with how the yggdrasil systemd service operates (https://github.com/yggdrasil-network/yggdrasil-go/blob/master/contrib/systemd/yggdrasil.service)

Research direction

Locate the yggdrasil package's service definition and compare its reload handling with contrib/systemd/yggdrasil.service, which is linked in the issue. Confirm how the package currently implements reload, then verify that reload sends HUP without removing the tun interface or its modifications.
