I submitted this patch because on CentOS 7, the usage 'service <name>
status -l' works;
and I found it doesn't work on Debian, without a warning.
I agree the service(8) command is a compatibility wrapper for many
different init systems,
so those systemctl specific options cannot be used with other init systems.
Adding a warning
message to tell user the options are ignored when invoking systemctl, if
any options are given,
should be also fine.
