           Summary: BR2_SYSTEM_DHCP is removed from .config and breaks
                    auto eth0

  Target Milestone: ---

Hi,

The BR2_SYSTEM_DHCP config is needed if you want the package ifupdown-scripts
to add automatic eth0 configuration to /etc/network/interfaces.

It's not available in menuconfig.
If you add it to the defconfig and make, it will be removed. You have to add it
to the .config manually and make if you want proper files to be generated.

I'm using a custom skeleton and busybox.

Why is it suppressed? Am I doing something wrong?

Thanks, happy new year!

Should I stop relying on these ifup scripts and use a custom script with dhcp
client at startup, as explained in https://busybox.net/~vda/no_ifup.txt?

I removed ifupdown scripts and emptied cd /etc/network folder and added an init
script that uses ifconfig up and down then calls udhcpc, I suppose it's the
preferred way.

Patrice,

BR2_SYSTEM_DHCP is only available if you use the default skeleton, and any
of busybox, ifupdown or systemd-networkd package.

If you use your own custom skeleton, you are responsible for providing the
necessary files (usually /etc/network/interfaces) in your custom skeleton.

Regards,
Yann E. MORIN.
