I'll second the recommendation of LVM. Taking it further: I use LVM for
everything except /boot. (And /boot gets its own space because most boot
loaders don't grok LVM, but also sometimes for security.)

It does everything one could want from any partitioning tool, and more.

Seems to be not widely known that one can stamp "whole disk" as a PV
rather than just a partition. For example, I bought a pair of 1.5T disks
for some matching content. What I did was 'pvcreate' and 'vgcreate'
against /dev/sdb rather than /dev/sdb1. Doesn't save any appreciable
amount of storage, but removes one layer of "stuff". Works.
