[arch-general] Long-term offline Arch system

Hi, I'm going out for a four month hike next spring, and will not bring my loved XPS with me. It struck me yesterday that being offline for four months is something pacman and yaourt might not like. How do these programs handle long-term stasis, will things break horribly when I come back and run an update? Is there anything I can do to avoid it? Best regards, Aron Widforss
