Maybe we should revisit microkernels
Sat 25 July 2026 misc Microkernels If you want a complete description of what microkernels are then read the wikipedia article, but in one sentence it's a kernel where everything is in userspace except for scheduling, managing access to I/O devices, and IPC.

Better security because in a muicrokernel system a bug in one driver only gives an attacker access to that subsystem (or maybe even that driver), as opposed to having unlimited access to the whole system like is the case with mainstream operating systems today.
