Could you explain what those LABELs are, and more specifically what creates
them and how does it map them to phsyical disk partitions?


Hi,

They are just strings that are supposed to avoid the need to have
the device names in the fstab.


Well actually they are used because the actual devices names can't be
used . There is no way ( found yet at least ) that anaconda can know the
actual device names for everyone .

For example i might choose to have /dev/hda2 as my root device ,
while you David ( for example again ) might choose to have /dev/hdc1
as your root device , so what would anaconda use as root device ?
This is where LABELS fit , so you have a LABEL= /root  and the
installation procedure gets simplified .

To create them you use 'e2label'.
As the name implies, this trick only works with ext2/ext3 filesystems.

Well it is safe to say in with ext2 filesystems , since an ext3 filesystem
is an ext2 filesystem with a journal ( ref. mke2fs -j .... )

Kind Regards,
  Kostas
