I'll add my $0.02US which (according to exchange rates) is
worth more though almost worthless.
Hate to say it but in this comparison LVM2 looses. Primary
reason: Backward compatibility. People are going to need to
be able to switch between kernels.
So far everything indicates that LVM2 is not compatible with
LVM. That LVM2 and LVM(1) can coexist-exist is irrelevant if
2.5 hasn't got a working LVM(1). And that would leave us
with having to do backup+restore around the upgrade.
Any on-disk changes also need to have an in-place translator.
Just think about what it would take to do an upgrade, or
downgrade, without in-place translation.
Also 2.4 -> 2.6 should not be a feature reduction so
snapshot volumes and any other LVM features missing from
LVM2 are issues.
