MAC address is different during arch live boot (installation)

Hello guys,

I'm unable to setup IP reservation for my device when in archiso mode.

When running `ip link show eno1`, i get this MAC (88:ae:dd:00:7c:ea), but on my DHCP server I got a totally different MAC(b6220feb00020000ab11f9acbf02e20f8096).

The goal is to run a ansible playbook when in archiso mode to install arch linux and then perform a post-install tasks to configure some additional things, but unable to do so because of bad MAC being sent to DHCP server.

How to tell the archiso mode to send always the correct MAC (ie. 88:ae:dd:00:7c:ea)?

Thank you

Hello.

The latter isn’t a MAC address. An MAC address is always 48 bit.

Perhaps the DHCP uses uses a client identifier.

Sometimes I seem a bit harsh — don’t get offended too easily!
