    <title>L3-L4 Microkernel Family</title>
    <link>https://e-sygoing.link/link/5680990-l3-l4-microkernel-family</link>
    <description>Lean, with fast, message-based, synchronous IPC, simply-used external paging mechanisms, security mechanism based on secure domains: tasks, clans, chiefs. Kernels try to implement only a minimal set of abstractions on which OSs can be built flexibly. L3 has system-wide persistence.</description>
