-q and --silent do the same thing. These are now documented in the
manual page for insserv.

Yes, older versions of insserv will fail if --silent is specified as it
will not be a recognized option. There should probably be a version
check. Or a check in the calling script to try with insserv --silent and
if it fails, try again without the flag.

The --silent flag suppresses warnings (non-fatal errors). Basically
anything that is a "heads up" warning is suppressed. Fatal errors and
issues which require user attention are still printed.
