| Ok, Ok, I have some real ideas to consider...
| 
| Idea #1 - umount the drives yourself:
| 
| 	sync;sync;sync
| 	umount -a
| 	shutdown -h now
| 
| Idea #2 - have shutdown wait a period of time before actually shutting
| down
| 
| 	shutdown -h +5  # Check my syntax on the +5
| 
| Idea #3 - some combination of the above ideas
| 
| 	sync;sync;sync
| 	umount -a
| 	shutdown -h +5

syncs aren't necessary if you're umounting the drive anyway. umount
causes the buffer for that device to be flushed before it actually
unmounts the device.
