everything thats not on a LVM volume sits here.  the biggest
is /root/.ccache (<800M, easily moved elsewhere) and /lib/modules

Its used by fbsplash - never looked at why

I have filled them in the past: my desktop is currently sitting at 74%
for both, but I recently went mad archiving to make room.

I have done that in the past - but I found sometimes I just had to have
the room (zipping 2G plus archives for instance)

extra complexity - I dont need remote mounts, and I am the main user.
If you use an automount on the same machine Ive gotta ask "why bother".
In my experience automount is just another thing that can and sometimes
does go wrong so it has to be justified.

Experience shows me that a single partition is almost maintenance free.
If you fill a disk, it does come to a halt but its easily fixed.  Ive
found inadequate a swap more serious problem.

Ive found that maintenance usually occurs far more often on
multi-partition systems simply because space that could be used is not
accessible.  Multi-partitions on the other hand always waste space
necessitating solutions like LVM.  For me LVM gives the advantage in
that I can add space (extra disks) whenever I like and fill it without
having to go through major pain.  In the light of experience, I am not
sure I will go for multi-partitions on my next server as laptops/small
desktop systems I run/have run seem better without it, but I will
definitely be going LVM.  I am sure that if I had a number of regular
users, a separate /home partition wold be useful but I think that the
old idea of partitioning everything is actually more wasteful/nearly
useless on modern systems.
