-------------------------------------
To cross-install current onto a separate partition
--------------------------------------------------
# In this approach we use a separate partition to hold
# current's root, 'usr', and 'var' directories. A partition
# holding "/", "/usr" and "/var" should be about 2GB in
# size.

To upgrade in-place from 4.x-stable to current
----------------------------------------------
# 5.x uses more space than 4.x. Also, the location of kernel
# modules has changed. If you are installing 5.0 onto a 4.x
# system, you'll need about 30MB of free disk space on your /
