I've been playing with wine64 under NetBSD 8.1_STABLE and it works surprisingly well with a couple of windows applications I need to run. Of course NetBSD-8 doesn't have support for USER_LDT baked in and so I have been testing under a NetBSD current kernel.
How much work would be involved in back-porting it to NetBSD-8? I know NetBSD-9 might be a better option, but in my experience kde doesn't work well with it :-( Cheers, Dave
