 |
|
Greetings,
I want my system to get it's dns from the router, I have a /etc/resolv.conf file with the router's ip, /etc/dhcpcd.conf has no resolve entry.
afaiu, that should cause the file to be auto regenerated every dhcp correct? note that I'm not using a systemd based init setup.
on my other systems (libreelec, alpine and debian), the file is auto regenerated.
any ideas what can be the issue?

| Compare the options passed to the DHCP client on the working and non-working systems. Check that /etc/conf.d/net does not disable taking DNS from the DHCP server. |

my other systems are systemd based, hard to compare

Other than, it's what command line options.
As you've noted, you've disabled resolv.conf population for br0 interface. |
I see, so I need to remove that entry, ok thanks!
