Hello, for a home computer that gets shutdown daily, I'd like to implement a function which:
1. makes sure that all pending outgoing mails are sent off. The system uses its local exim to send mail over the (slow) net, and I don't want to pull the plug on longish emails that are being sent. Essentially the shutdown process should stop and proceed only after exim is finished with its business. Is running "exim -q" enough for that? 2. makes backups of all user home directories. For this I'd prefer the system to be in single-user mode so that no files can change dureing backup (in reality this is not so important because nobody does anything on this machine after X has shut down. While I know how to properly write an init script (I'm going to rely on the Debian policy for this) I'm unsure as to the runlevel these actions should be taken. The exim thing of course must happen before the network shuts down and the backup should be the last thing before the disks are unmounted. Suggestions, anyone? --D.
