i now tested this many times on VM (vbox) http://wiki.archlinux.org/index.php/Package_Proxy_Cache everything seems to work ok. but i found some other issues with custom AIF profiles (in automatic mode) # aif -d ... gives me the aif usage info # aif ... -d runs aif but doesn't do any /var/log/aif/debug.log but whats more annoying, the base packages get downloaded in 5 seconds, but adding like xorg to TARGET_GROUPS or TARGET_PACKAGES, those packages take like 15 minutes to download, even when all come from the proxy cache... (would be nice to know if this is like that on other systems, or is it just so in my setup) and i also wonder whats the difference between TARGET_GROUPS and TARGET_PACKAGES ? but other than that, i'm really happy to got this far :) cheers .andre ps. please do video record this ;) http://www.archlinux.ca/archcon2010/?p=67
