Attaching drives by serial number: HOWTO

The 2.4 release will attach disk drives by serial number.  Matthew Dillon’s written up a quick HOWTO that describes how to use it.  The interesting effect, as he notes, is that a drive can be attached in almost any way – a firewire enclosure, directly to the motherboard, through a card, etc. – and the machine will still happily boot without any changes needed.
