From 9ecd27ddbbbc252c50e1ccdeb9a8e35c67ce7e25 Mon Sep 17 00:00:00 2001 From: abdosi <58047199+abdosi@users.noreply.github.com> Date: Fri, 6 Jan 2023 18:36:37 -0800 Subject: [PATCH] During build time mask only those feature/services that are disabled excplicitly (#13283) What I did: Fix : #13117 How I did: During build time mask only those feature/services that are disabled explicitly. Some of the features ((eg: teamd/bgp/dhcp-relay/mux/etc..)) state is determine run-time so for those feature by default service will be up and running and then later hostcfgd will mask them if needed. So Default behavior will be init_cfg.json.j2 during build time make state as disabled then mask the service init_cfg.json.j2 during build time make state as another jinja2 template render string than do no mask the service init_cfg.json.j2 during build time make state as enabled then do not mask the service How I verify: Manual Verification.
