It looks like Ubuntu put something in to attempt to deal with this.
Instead of listing disks by path in /etc/fstab, they use a UUID:
UUID=342c5e8f-efcc-4636-9845-010ec2d20b7c / ext3
defaults,noatime,errors=remount-ro 0 1
This seems like a good idea, as the UUID is not supposed to change if
you change from /dev/hda1 /dev/sda1, but I actually ran into an issue
with it recently.
I changed the size of my swap partition and that, combined with my
unawareness of /etc/initramfs-tools/conf.d/resume made the UUID of my
swap partition change, causing my machine to not see my hibernate
image when resuming and not mount the swap space.
A little digging seems to indicated that mkswap generates a UUID. My
response was to change my fstab and /etc/initramfs-tools/conf.d/resume
to use the device path rather than the UUID for my swap/resume
partition since at least that doesn't change when I change the
contents of the partition.
