Re: How can I avoid completion using chkconfig on RHEL10?

I can't really see much wrong with _services. Perhaps the chkconfig
branch could be removed.

The main problem here is that command_not_found_handler() is apparently
run for the chkconfig command and produces output regardless of the
/dev/null redirections. I'm not keen on wrapping every use of an
external command in completion with checks for the command, partly
because of the inherent race condition. For software in general, it is
usually better to just try and handle the errors as they occur than to
check first: chkconfig --list >/dev/null 2>&1 should fail silently.

I've never as such made use of a command_not_found_handler. Presumably
it is intentional that it is invoked for commands that are run
indirectly? Can or should it be disabled for the completion system? What
about for all functions?
