Yes, busybox was for sure a bad choice for maemo but continue to rely on his cutted and violated gnu replacements is something that creates confusion and problems hard to debug

@ade
yes, you are right, a developer can't consider any possible alteration.
But when i approach the idea to create a script with "find" i have in my mind the gnu find behavior, not the busybox one.
Then, when i discover the difference bumping my nose against it, i try to use a syntax that can be valid for both of them(gnu and busybox) ...And i think this should be important especially for a system tool.

Edit:
This doesn't mean that everything using busybox is crap.. I only think that things could be designed to match a more extended (and foreseeable) set of situations.
..In fact, it seems i'm not the only one that tried to replace the busybox functions' symlinks with the original gnu tools.
