I'm not a Sys-admin -- just a long-time user -- but I like this partition
mapping
because /usr, /tmp, and /var are on their own partitions. I see there's plenty
of
room in /usr, but / (root) is filled up (yuck).

Before doing any major surgery, I would find out why root is filled up --
you've allocated almost a half-gig to it. If it's a just a handful of big
files
or a single big directory, then I would move them to /usr and then add a link
pointer
to them from / (root).

If you want to do minor surgery, I would suggest "ext2resize." I successfully
used it to expand a partition, but it takes careful understanding of the
relationship
between blocks and cylinders.
