When I first set dustpuppy up for multi-site webserving, I had envisioned using a locally-maintained drupal build. That got to be too difficult to keep up patches for all the modules that had to be manually unrolled and installed. So I went with the Red Hat repository install of Drupal 5 (which installs in /usr/share/drupal), which keeps the base system, themes, and core modules updated automatically with the rest of the system. It works great and I have no problems.
But now I have 496M allocated to /var/www that’s doing nothing. It has a no-longer-used local copy of Drupal 6, the apcupsd web interface (which isn’t even configured), a mirror of the Jargon File, and the ridiculously resource-hogging website CPU usage analyzer that’s disabled because it grinds the machine to a halt when I use it.
I’d like to keep this space around in case I ever do get a webapp that runs out of /var/www instead of /opt or /usr/share. But at the same time, I could put that ~500MB to better use.
Then again, this is on a .75TB RAID array so does ~500MB really make that much difference? It adds up to 0.06% of the total space.
