Title:
  systemd-resolved generated resolve.conf gets comment spam with high
  numbers of seach domains

Status in systemd package in Ubuntu:
  In Progress

Bug description:
  When a large number of search domains are configured in a *.network
  file the auto-generated /run/systemd/resolve/resolv.conf file is
  spammed with commentary for each and every dropped search term.

  # This file is managed by systemd-resolved(8). Do not edit.
  #
  # Third party programs must not access this file directly, but
  # only through the symlink at /etc/resolv.conf. To manage
  # resolv.conf(5) in a different way, replace the symlink by a
  # static file or a different symlink.
