Well, if they have already partitions to reuse ( ie, ex centos
partition ), they will just reuse them without lvm and that's all. And
if they do not have any partition to reuse, or just a part of the disk,
we are in the same case, there is free space and we can use it as we

And what exactly would be broken with lvm and theses schemes ?
Arguments based on "there is some special cases that would requires
special care" are not very helpful if the special case is not described
in details, and we cannot have technical discussion based on imprecise

Making it be default doesn't mean that the user cannot decide to opt
out, this argument do not seems very strong.
This is a default, not something that would be forced to use.

the lvm, and one outside ( or several, or any mix you want ).
