I found a couple of problems with the original patch, the new patch that I'm attaching should fix them. The new patch will also only download a new script if svn info returns a different checksum than the local file, so it will only download the scripts that are actually different in the repository. I have just finished upgrading to 4.8, and I'm in the process of using it to install a machine. I haven't yet changed the config.pl to use the postgresql database. -- Thanks: Joseph Rawson
