Linux Device Naming

[Jimmy Stewpot]

Hello,

I am currently working on a system where there are loads of fibre 
channel devices being attached and disconnected at regular intervals 
(test environment). Currently when the system boots and fibre channel 
drives are connected it will detect those LUN's first and the on-board 
scsi local drives will be detected last. That means that we have things 
like / being on /dev/sdg1
Is it possible to have persistent naming so that the system disk is 
always /dev/sda ?

Regards,

Jimmy
