Labels do help for the root device but not for ephemeral devices in
EC2:- with an EC2 instance you'll know the label or UUID of the root
device but ephemeral devices are created at startup time. This makes
getting mountpoints right hard if you're programmatically starting
instances difficult.
There's also a 'mapping' between what the EC2 APIs return as the root
device (helpfully still referred to via the old SCSI names), again
which makes programmatic operations break: expecting something to
be /dev/sda1 in EC2 that was /dev/xvda1 in the instance but magically
now is /dev/xvde1.
Anyway as I say it's definitely a problem with upstream so we'll just
wait and see. Just explaining this here so that the search engines get
it and it'll hopefully help someone else with the same problem in the
future.
Cheers,
Steph
