I do this when a periodic files system check of a large partition kicks in and I do not want to spend the time waiting for it. Other things I like to interrupt are long timeouts, e.g. while some program waits for a server to respond, but I do not have an internet connection at the moment. I had this problem with an annoyingly large NTP timeout (it seems to be much smaller these days), and I wished I could have stopped it. Wonko
Re: [gentoo-user] [OT] interrupting runscripts during startup
My interest is foremost trivial. Not necessarily related to the application of such interrupts. Nevertheless, with regards to the post: * runscripts can (and AFAIK do) trap and handle SIGINT. * the interactive mode is ok for interrupting the init process between scripts. But I can't interrupt a script while it's running with 'I', and with SIGINT, I can.

Hitting CTRL-C stops the script somewhere in the middle during its execution. Everything that was done until that moment won't be automagically undone. There can be files left , and processes already started will still run. That's not clean. Better use the interactive init feature. Just hit 'I' when init starts (init even tells you, that you can do it) and choose which services to start by hitting 'y' and 'n'. Cheers, Renat
