RE: Which device did I boot from?

[Dallas Clement]

In fact I am trying to boot from a USB drive which would be /dev/sdx.

The other problem I have is that I can't just do a search for a
particular file like devices.map on a mounted partition. 

I may wish to install over the top of an existing IDE drive, which might
also have grub installed and a corresponding menu.lst and devices.map.

So it's very difficult to tell which one of several possible devices was
the boot device by just examining the contents on the device.
