Sorry for what is probably a faq, but I'm not clear on the best way to migrate my old /opt and /usr/local to a new MacBook? I have a ton of stuff in there that I can't easily reinstall, for example an entire Gentoo distribution compiled (painfully) from source. Maybe just use tar? The source machine is a first-generation MacBook currently running 10.8.5 and the destination will be the new generation MacBook. ---------- Just realized this should probably have been posted in the OS X section. Sorry about that.
