Of course I followed those steps. That's what makes me think something is not working the way it is intended. After installing a recent snapshot, I checked out /usr/src and did a make build. I thought this leaves me with a pre built tree I can just build incrementally. Indeed this is working. So, after a cvs -q update -dP -A I just cd'ed into the directories containing files with changes and did make followed by doas make install. Also in /sys/arch/amd64/compile/GENERIC.MP. This has been working as expected. I then accidentally ran make directly in /usr/src which is failing due to some Permission denied I do not understand. I can still run make install in /usr/src without issues. > > 3. You might want to consider not building from source, but install a > snapshot by running sysupgrade -s. I am keen on knowing how those snapshots are build. Do they really wipe out everything and then do a fresh build - lasting nearly 24h here for me. I doubt it. > > -Otto -- Christian
