Yeah, definitely ironic ... The Via machine basically only gets security updates. With only 256 MB of RAM, it's probably too wimpy to self-host, and I hate to think about how long buildworld would take. I cross build releases on a more modern machine and use a custom freebsd-update to keep it up to date, with itself is a PITA. I think packaged base would be less of a hassle. The laptop gets more frequent updates and is able to self-host. Doing buildworld + buildkernel takes a really long time. It looks like my last buildworld (11-STABLE) took nearly 14 hours. This was my fastest machine for quite a while. I'm planning on doing an update this weekend in preparation for an upcoming trip. > On a related note, did you measure how much (e.g. in terms of battery > life) your laptop gains from using the UP kernel?
