maybe you're right. shrug. does your script change the working directory? do all systems have fancy core file management now? does it still cause issues with unmounting?

it is true that it's rare to see a daemonize flag these days...

This all depends on what the program does. If you have some app specific service that waits for postgresql NOTIFY messages, and does something in response, it doesn't matter that working dir is not /. You just stop the service and perform maintenance.

If it's something like sshd, it better not prevent any filesystems from umounting unless necessary.
