7.0beta4: "/etc/rc.d/rc.samba reload" not applying Tailscale IP

I reviewed the diagnostics file that this user provided and can see that the Tailscale IP is being added to smb-names.conf as expected. However, Samba is still not listening on the Tailscale IP after the reload.

It seems that reload-config might not be applying the interfaces. If this is the case, a race condition is created between the array and Tailscale, particularly if auto-start is enabled:

1. If Tailscale obtains an IP before the array starts for the first time, Samba works correctly.
2. If the array starts before Tailscale obtains an IP, Samba will not respond on the Tailscale IP, even after it is reloaded.
