You answered my question --- I didn't know about blkid utility.
With this one can give every partition a meaningful labels like ---
LABEL="hda1"
or whatever is displayed as the system device one one runs blkid
without options in order to get a full listing. e.g.
cmpq:~# blkid
/dev/hda1: UUID="990189bc-f7ce-41a6-9d8f-64a35349875e" TYPE="ext3"
/dev/hda2: LABEL="HDA2" UUID="5a02e986-8aa3-4790-aa3f-41f7f565533f" TYPE="ext3"
/dev/hda3: LABEL="HDA3" UUID="63025622-0210-49d4-89ff-f038e6c218b6" TYPE="ext3"
/dev/hda5: TYPE="swap"
/dev/hda6: LABEL="HDA6" UUID="12148027-bc0b-4260-853e-64a8d79c6fe7" TYPE="ext3"
/dev/hdb1: UUID="29b36e91-32e7-46bd-b8d3-831f5dcbd337" TYPE="ext3"
/dev/sda1: LABEL="WDMB-1" UUID="bc1d2170-d790-4952-bbee-c3c3efdd8413" TYPE="ext3"
/dev/sdb1: LABEL="WDP-5" UUID="8c6c3be3-4a72-45cd-929f-2dec9f185427" TYPE="ext3"
Gah!!! "HDAn" are *horrible* labels.
When you add another hard drive, the kernel might make it hda and
your existing drive hdb. Or libata might convert them to sdx and
then you'd have sda2 with label HDA2. *Very* unintuitive!
Or you might need to move the drive to a machine that already has a
partition labeled HDA2.
Give them meaningful *symbolic* names.
This is from a system that is running Lenny. Note that the swap partition doesn't
have either a label or a uuid, but I had specified labels each time I installed
a distro.
That's weird.
