They are a complete > reality today. Maybe dynamic device numbers are bad idea to start with? I'd like to keep static /dev, thank you... With big enough major/minor space (which we have today, I believe), complexity of dynamic device numbers can and should be avoided. Plus... this patch 'hardcoded' device names. Why not 'hardcode' device numbers in the same way, so that static /dev keeps working? Namespace should be big enough...
