Yes, my point was mostly that in order to support older kernels, most
code is going to want to just access /sys/block/DEV/DEV*N/ anyway. What
I have done in my code is I do a readdir() on /sys/block/DEV and look
for subdirectories with a "dev" member.

Changing them to symlinks would actually break at least my code
(arguably bad programming on my part), since optimize by looking for
