It would, if a tested script came that either worked identically
with all distributions or adapted to the quirks of each. 
Otherwise the script becomes another place you can make
the typos.

Yes, but the point of a distribution should be to save the
sys admin's time, not invent new quirks he has to work around.

Eliminating the labels and using the partition device names that
are always unique gets rid of the whole messy concept.

Beg you pardon?  Can you imagine a commercial product vendor
saying that causing problems is to be expected?  Yet you
probably think that Linux distributions should be usable in
most of the same situations.

Learning to compensate for unique quirks is never a good
thing for anyone.  It was a waste of everyone's time and
will be meaningless when you find a better distribution
or this one finds some other quirky way to compensate for
barely-deterministic scsi device names.

But you learned something that will soon be useless to know. And
how to you know you've found all the quirks yet?  Did you run
across where the MAC addresses are stuffed so they screw up
systems after you move the disks?  Maybe there's more that
we haven't hit yet.

The crusade is for a philosophy of making a distribution that
can actually be used in any scale.  I just have a hard time
believing that whoever came up with idea of putting labels
in fstab actually maintains an assortment of machines.  And
the same crusade should apply to whoever is deciding to move
a random assortment of files to new and equally arbitrarily
different locations in each release.  Either get all the
distributions to agree on a standard and do it at once or
leave things alone.  And please document everything under
/etc/sysconfig - something that hasn't been done since
RH9 even though it is vastly different now.

Surprises aren't fun for anyone.
