You don't have to shutdown services but you have to restart
them. The problem is that an pgrade will delete libraries (replace
them with newer version) and the running services keep the old file
loocked in a shadow existance. The filesystem can only actually delete
them once nobody is using them anymore. And that prevents the
filesystem from being remounted read-only.
On the other hand how much fun is having the system crash or doing a
scheduled reboot and suddenly services don't come back up anymore
becuase 6 month ago you upgrade libfoo? I rather prefer restarting all
services or even rebooting after an upgrade. At least at that time I
still know what I updated and can reverse it (from backup?).
