[yocto] Sumo distro problem with dhcp packet?

[Zoran Stojsavljevic]

Hello Kosta,

As said, I have tried instead core-image-base ==>> core-image-minimal
one on the target platform, which is BBB. To my surprise it is in
there (in the minimal initramfs)!

Since the eth0 IP address upon sumo booting is all wrong, I have
tested the BBB dhclient command as:
# ifconfig eth0 down
# dhclient eth0 -v

And it works perfectly, brings eth0 up, sets the correct IP address,
and then goes for lease with dhcpd on the another side.

So, what is here catch 22 (why base image does not have dhclient, and
minimal does)?

Thank you,
Zoran
