could be handy for those 'I see a few messages that scroll, and the
box instantly reboots' bugs. Quite rare, but they do happen.

Another very common situation is a system which fails to boot due to
failures to find the root filesystem. This can happen because of device name
slippage, root disk not being found, the proper HBA driver isn't present in

mount by label fixes some of that but not all

there appears to be a limit on how many disks get checked for their label. I've got one system where I've got 2xraid cards each with 8 drives on them and then another raid card with my boot disk on it.

depending on how I have the two raid cards the boot disk can be anything from sdc to sdq, mounting by label works for sdc, but not for sdq.
