Two general points I can add: 1. Sharing config files turns out to be really hard. By far the easiest way is to just share /etc but that is an all or nothing approach, and you just need one file to be different to break it. Like /etc/hostname You *could* create a "share" directory inside /etc and symlink common files in there, but that gets very tedious quickly. Rather go for a centralized repo solution that pushes configs out, you must just find the one that's right for you. 2. Binary packages are almost perfect for your needs IMHO, running emerge gets very tedious quickly, and your spec is that all workstations have the same USE. You'd be amazed how much time you save by doing this: emerge -b on your laptop and share your /var/packages emerge -K on the workstations when your laptop is on the network step 2 goes amazingly quickly - eyeball the list to be emerged, they should all be purple, press enter. About a minute or two per workstation, as opposed to however many hours the build took. 3. (OK, three points). Share your portage tree over the network. No point in syncing multiple times when you actually just need to do it once. > > I'm soaking up a lot of your time (again).
