Status in systemd:
  Unknown

Bug description:
  [impact]

  resolved does not ignore comments properly in /etc/hosts

  [test case]

  see original description below

  [regression potential]

  as this modifies resolved parsing of /etc/hosts, regressions would
  likely be in hostname lookups from hosts in /etc/hosts, or failure(s)
  to parse /etc/hosts correctly.
