Subject: cleaner logic, fix things so that fw_update -da makes sense
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=e1b321ad6e4e2a58ba35849ff5e3e2080562af04;p=openbsd

cleaner logic, fix things so that fw_update -da makes sense
(deletes drivers not corresponding to that box, and updates/installs what's
needed)
