You don't specify if you boot off the onboard flash, via nfs or something else.
If you boot via nfs, the kernel does the initial dhcp request to get the root filesystem, so it won't write anything into resolv.conf - that you would have to do with another dhcp request, taking care not to deconfigure the interface, otherwise you use your filesystem (as it is set up via nfs) - best is to keep the resolv.conf set up remotely. Generally, strace is helpful, it will tell you what configuration files an application opens regards marc On Fri, Oct 16, 2015 at 2:56 AM, Simon Dicker <simon.dic...@gmail.com> wrote: > This should be a simple one - where/how does a roach1 store its network > settings?
