I am wondering how I can configure an Arch Linux system to mount an external hard disk when it is plugged in (as opposed to have it plugged in at startup).
In order to to that, I added
/dev/sdb1 /mnt/E auto rw,users,umask=0000 0 0
Although I specified
auto, it wouldn't automatically mount the harddisk when I plug it in. In fact, the system wouldn't even boot up without the harddisk being plugged in.
