Description Yuxin Sun 2021-05-26 10:02:51 UTC 
Description of problem:
If not install dhcp-client, cloud-init fails to provision VM on Azure. Suggest to either add dhcp-client to the cloud-init dependencies, or fix cloud-init to not rely on dhclient.

Hello Eduardo,

is there a plan to add the dhcp-client dependency to cloud-init? We (the Image Builder team) think that this is the best option. If this is a problem for you, we need to know it sooner rather than later so we can change the image definition for Azure images in 9.0 Beta.

Thanks,
Ondřej
