However, seeing it seems to recover only a handful of numbers with some significant complexity required it seemed like a stopgap solution anyway. I posted a proposal in this thread that simply extends the dynamic range into a region above 256 which seems to work well. This means regular configurations won't be affected an any configuration requiring more than 20 dynamic majors will simply end up with high numbers. So unless anyone can think of a reason why this won't work, it's my preferred direction. > Making them all dynamic seemed dangerous because I was afraid > of userspace ABI breakage because of old userlands with > static mknod:s. I agree.
