  14 # Note that this tool doesn't need CAP_SYS_TIME itself, but it's primary
  15 # usecase is to run in conjunction with a local NTP service such as
  16 # systemd-timesyncd.service, which is conditioned this way. There might be
  17 # niche usecases where running this service independently is desired, but let's
  18 # make this all "just work" for the general case, and leave it to local
  19 # modifications to make it work in the remaining cases.
