So you're using /dev/disk/by-uuid/<uuid> in /etc/fstab?

I'm confused. Doesn't every disk have symlnks in /dev/disk/by-id (even
LVM LVs)?

multipath.udev sets up these links for persistent device naming:
# Create persistent links for multipath tables
ENV{DM_UUID}=="mpath-*", \
SYMLINK+="disk/by-id/$env{DM_TYPE}-$env{DM_NAME}"
# Create persistent links for dmraid tables
ENV{DM_UUID}=="dmraid-*", \
SYMLINK+="disk/by-id/$env{DM_TYPE}-$env{DM_NAME}"
# Create persistent links for partitions
ENV{DM_PART}=="?*", \
SYMLINK+="disk/by-id/$env{DM_TYPE}-$env{DM_NAME}-part$env{DM_PART}"
This is what should idealy be used in d-i for multipath device naming.
We could then start to remove the hacks that use /dev/mapper/mpath* to
reference multipath devices then.
I'd be happy to help to get this working for Squeeze.
Cheers,
