[TriLUG] Any Kubuntu/Ubuntu users explain to me why my IDE drives show up as sda?

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:

# /dev/sda1
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.
