As per poll(2), all errors except `EINTR` (which we already retry) are not runtime errors, but programming errors that ought to be fatal. The only edge case is maybe `EINVAL`, but if our `n_fds == 1` is already exceeding RLIMIT_NOFILE, we are in deep trouble anyway, and exiting is still the right thing to do. With that, change `wait_for_io()` to return a bool, so that error handling in the caller becomes simpler and more robust.
Cockpit
A sysadmin login session in a web browser
Cockpit is an interactive server admin interface. It is easy to use and very lightweight. Cockpit interacts directly with the operating system from a real Linux session in a browser.
Using Cockpit
You can install Cockpit on many Linux operating systems including Debian, Fedora and RHEL.
Cockpit makes Linux discoverable, allowing sysadmins to easily perform tasks such as starting containers, storage administration, network configuration, inspecting logs and so on.
Jumping between the terminal and the web tool is no problem. A service started via Cockpit can be stopped via the terminal. Likewise, if an error occurs in the terminal, it can be seen in the Cockpit journal interface.
You can also easily add other machines that have Cockpit installed and are accessible via SSH and jump between these hosts.
