I'm sure the writers won't ignore the old partitioning methods, but LVM
is recommended for all installations, including laptops and non-servers.
Using LVM makes it possible to reallocate space as you need it on any
system.  I have frequently made use of this capability on my laptop,
where the older partitioning method would have created an enormous
headache, if not inviting outright disaster.  Anaconda defaults to LVM
for very good reasons! ;-)
