Arch on external hd

I have arch installed on my 40gb exterbal hard drive. The 'root'  filesystem is defined as /dev/sda1 in /etc/fstab.

The problem is that depending on a pcs config, this changes. For example if another pen drive is plugged in it may be ./dev/sda1 instead and boot will fail. The same happens if a SATA hard drive is installed - they register as /dev/sdx.

I get dumped to a command line where i have to remunt / rwx, edit fstab and reboot. This gets annoying, how do live cds, and other distros that boot from pen drives get around this?


Also on a differnet note i cant get  a working xorg.conf, Xorg -config creates a file but when i use it all i get is a black screen with the default X cursor. I can run Xorg without xorg.conf but at the moment its not displaying enough colours- i  can see lines on gradients.

I run Xfce4 and previously the problem went away when i uinstalled xorg-video-drivers, but after a comlete reinstall the problem persists.

Again how to pen drive based distros and live cds get around this?

Any ideas?

You could create a udev rule, so your external HD will be mounted in the same place every time.  Check the WIKI for more info.

Device names in my case are creating when initrd loading and another problem with boot manager if you have several usb-keys or drives their names will change if you plug them in different usb hubs.
