No, don't do that. Every method to “clear the aegisfs mounts” that I've read has been more stupid than the previous one. Remove the aegia mounts and you will get weird bugs ranging from slow GPS locks to higher battery usage (because of processes crashing repeteadly in the background). My N950 has been aegis-less for a while (removed from the kernel and userspace libs) and there are plenty of randomly placed calls to Aegis that will fail if you do the above. Just reflash, dammit. Its not that hard and you do not have to do anything afterwards. If you really want to avoid reflashing, at least use apscli. But then, please, don't.
