System hangs during shutdown
I wrote a short script and named it "umount_<device-name>/sh"
#!/bin/bash
#script for automatic unmounting of nfs drive on reboot and shutdown
umount /<mount-point>/<device-name>
exit
That script goes into /etc/init.d
sudo mv <dir>/<"umount_device-name> /etc/init.d
The command umount /<mount-point>/<device-name> needs to be the appropriate command to unmount the network drive. You can test the command from a Terminal by running it as root (sudo on Debian/Ubuntu) and check that it actually does unmount the device.
A syslink then needs to be made in /etc/rc0.d
The name of the link needs a "K" number adding onto the start. The "K" number sets the priority and needs to definitely be before the network is shut down. I set it to be the first thing to shut down by calling it "K20umount_<device-name>" ("20" is a higher number than any of the existing link names).
sudo ln -s /etc/init.d/umount_<device-name>.sh /etc/rc0.d/K20umount_<device-name>.sh
Reboot.
Disable annyoing system beep during shutdown
1. Install "gnome-alsamixer" and start it
2. Find the "Beep" device and mute it (lowering volume does not help)
