The only archs we may be interested in are x86(_64), arm64 and power64. The rest is for cross-compilations. Docs? Can be deleted. fs? ext4 is ~1.7 MB. Do you need heavy file systems (xfs, btrfs)? If not, can be deleted. Drivers. net > 100 MB. But do you need drivers for expensive low-latency server network cards on your laptop or home workstation? You can always compile such a driver outside of the kernel. gpu >250 MB. In many cases it can be deleted as well. So if you only choose what a typical user may actually be interested in, such a striped-down kernel may be less than 100-150 MB or ~10-15 MB as gz or xz. Updates? It is not that difficult. The rule is simple: if it doesn't touch the remaining code, skip it. > But OpenBSD is still REALLY fat If I remember correctly, version 3.8 was the last one with the minimal option. Later it was only fatter and fatter. OpenBSD is no longer a lightweight solution. It's probably easier to configure Linux kernel than to do a lightweight OpenBSD installation (perl for pkg, clang/llvm etc).
