76 # googling around a bit finds 2 main solutions:
77 # http://askubuntu.com/questions/3503/best-way-to-cache-apt-downloads-on-a-lan
78 # apt-cacher-ng doesn't have zeroconf.
79 # It touts having minimal dependencies, but I don't care.
80 # The downside to squid-deb-proxy is that it's config is for specific repos,
81 # you have to add all the repos you use.
82 # That is the main reason I use apt-cacher-ng.
83 # It has a web portal, at http://faiserver:3142/acng-report.html
86 # random fai note: as far as I can tell, profiles are just for putting
87 # in a selectable boot menu, which I don't want.
89 # the logsave prompted because the hostname faiserver was uknown.
90 # Here it was faiserver.lan when running from a faiserver vm.
91 # When running from a normal host with faiserver alias, it was the normal hosts name.
