There was no standard, every system behaved in a subtly different way, and there were a few userland initiatives to get decent randomness, all incompatible of course. The situation is a bit better now, we're heading towards some standardization. The arc4random() series of functions is a good API, and available on a lot of systems - unfortunately not Linux, but on Linux the new getrandom() makes using /dev/random obsolete. So I removed the old crap in librandom, dropped EGD support, dropped dynamic backend selection, made a single API series (random_* instead of goodrandom_* and badrandom_*), added an arc4random backend and a getrandom backend, and defaulted to /dev/urandom backed up by SURF in the worst case. This should be much smaller and logical. However, it's a major API break, so the skarnet.org stack will be changed to adapt.
