By choosing packages carefully, it is possible to use linux in applications that need to meet SIL1 or SIL2 criteria [1]. I personally don't have any applications that need to meet SIL2, but it is possible to meet SIL1 by taking a normal installation and removing a bunch of stuff (initramfs, udev and inetd amongst others) until the system is deterministic enough (see the methodology in [2]). /sbin/init functions OK with a few static devices in/dev
Given the tight udev/systemd marriage and the undeterministic nature of socket activation, I suspect that systemd will never be suitable for SIL applications. Are there any other debian embedded developers that need to meet SIL criteria? How are you planning to manage the fact that there are very few non-systemd distros left, or do we have to resign ourselves to a life of OpenEmbedded and buildroot?
