This causes issues for log collection setups where the collector does not run as root but instead relies on group access to the watched daemon’s log file. Introduce a new option that allows specifying the output file mode using install(1)-style semantics. This enables non-root log collectors to access the file as intended and improves compatibility with log rotation tools.
