On Debian we lost the ability to control resolv.conf throughout ansible bootstrap. It is observed how renewing leases will override DNSs configured during ansible bootstrap. Problems will surface when later in the boostrap docker images are downloaded, because information related to DNSs was overwritten by dhclient. This behavior is different than on CentOS. Align behavior with CentOS. In fact align with how the design should be: control resolv.conf throughout bootstrap and don't let external factors change it during that time. Created a patch and updated the format(git am compatible) for an older one. Test on AIO-SX: PASS: build-pkgs && build-image PASS: custom test using dhclient for OAM interface. Forcing lease renewal to 10 seconds for quick tests. Without this patch it is observed how resolv.conf is updated by dhclient after resolv.conf is changed as per requirement to solve custom domains. With this patch it is observed how resolv.conf is not updated anymore.

Subject: [PATCH 1/2] dhclient: dhcp6 set hostname
|
|
|
|
The dhcp upstream commit 9261cb141 introduces a function
|
|
set_hostname() set host name, and the commit also implements
|
|
the DHCPv6 Handlers, so insert the set_hostname to the
|
|
BOUND6|RENEW6|REBIND6 implementation.
