Matthew Dillon noted in this post to kernel@ that he anticipates 64-bit work in perhaps 6 months, after VFS is completed.
The really evil thing about this is that I don’t know which I can’t wait for more! Irritatingly, it’s going to take a couple more years, but likely by their third year, DragonFly will be very damned impressive.
Well, it is going to be impressive much earlier IMO. But the additional delay allows us to add the necessary infrastructure for good 64bit support first and therefore be better prepared for the actual introduction.
