Subject: [PATCH] sysconfig: distro-specific config rendering for BOOTPROTO
 option (#162)

RH-Author: Eduardo Terrell Ferrari Otubo (eterrell)
RH-MergeRequest: 1: sysconfig: distro-specific config rendering for BOOTPROTO option (#162)
RH-Commit: [1/1] d88e3e93e2d23c8b90191cf6c5d0e8b7733fcce2 (eterrell/cloud-init)
RH-Bugzilla: 1931835

commit 06e324ff8edb3126e5a8060757a48ceab2b1a121
Author: Robert Schweikert <rjschwei@suse.com>
Date:   Mon Feb 3 14:56:51 2020 -0500

    sysconfig: distro-specific config rendering for BOOTPROTO option (#162)

    - Introduce the "flavor" configuration option for the sysconfig renderer
      this is necessary to account for differences in the handling of the
      BOOTPROTO setting between distributions (lp#1858808)
      + Thanks to Petr Pavlu for the idea
    - Network config clean up for sysconfig renderer
      + The introduction of the "flavor" renderer configuration allows us
        to only write values that are pertinent for the given distro
    - Set the DHCPv6 client mode on SUSE (lp#1800854)
