Can I set a different host-name for eth0 and wlan0 while using comitup?

Hi,

First of all, thank you for creating this software, it's been so much easier to use than trying to make my own solution.

My question:
I saw somewhere that you have your own dhcp configuration file in dns-connected.conf and was wondering if there's any way to specify a hostname for ethernet and wlan similar to the send host-name argument in dhclient.conf?
My RPi will often start out connected to both wlan0 and eth0, and I would like to make sure I connect to it through the ethernet interface in that case.

Simply disconnecting wlan0 when ethernet is connected would also be a good solution for me, is that easier potentially?

Thanks for your help!
Vincent

This issue has come up before. It is not actively being worked.

If this is a concern for you, you could weight the ethernet route to ensure it is the one that is used.

Thank you for the answer!
In which file should I add the weight? I'm under the impression that you don't use the standard dhcp files for comitup, or is that not right?

It is stored in a connection file in /etc/NetworkManager/system-connections.
