Thanks, I'll try those.

Due to the way the Jenkins job were setup, we always start from a clean
environment, so that means re-downloading everything every time.

For templates using http that's not a big problem because I have a
gigabit Debian and Ubuntu mirror on site and I have a gigabit squid
proxy for any other http query. The problem with plamo is that you're
using ftp which doesn't get through the transparent squid...

Anyway, it's not a huge problem as we're only building two plamo images,
so an hour of download time a day is no that problematic. If we had 20
builds, then it'd definitely be a rather big problem :)
