the follow paragraph is duplicated on the "C.2. The Directory Tree" (rev 532 is http://bazaar.launchpad.net/~ubuntu-core-dev/installation-guide/ubuntu/view/head:/en/partitioning/tree.xml#L128):

"""
It is now recommended to have /usr on the root partition /, otherwise it could cause some trouble at boot time. This means that you should provide at least 600–750MB of disk space for the root partition including /usr, or 5–6GB for a workstation or a server installation.
