Bug 217191

Description of problem:

I dried to update my FedoraCore5-Installation to FedoraCore6.
I bootet my system from dvd for installation, and when anaconda found my
fedoracore5-installation I decided for update.
But update failed because anaconda did not find the partition labels from
the LVM-logical volumns.

Original after installation of Fedora Core 5 I had no "LABEL=" in the file
/etc/fstab, so the line:
LABEL=/     /              ext3    defaults        1 1
looked like:
/dev/dm-0   /              ext3    defaults        1 1

I labeled all the logical-volumns with e2label and changed all the
/dev/dm-? stuff in my /etc/fstab to "LABEL=" by hand
and I think this is the problem why anaconda now is not abel to find
the lvm-logical volumns.
If I do a
# dumpe2fs -h /dev/dm-1 
I get the following output:
------------------------------------------------------------------

Version-Release number of selected component (if applicable):


How reproducible:
After Fedora Core5 installation:
Label your lvm logical volumns with e2label and change all the
/dev/dm-* stuff in your /etc/fstab to LABEL=TheNameyouGavetotheVolumn
Boot for Installation from the fedoraCore6 dvd and after anaconda found
your old system (fc5) decide for update.


Actual results:
anaconda will fail because anaconda will not recognise your lvm-logical volumns
by the label-names.

Expected results:
