Let's refresh this thread. It looks like (at least for stable/14) build system doesn't hardcode revision into the kernel anymore. Last time it worked to me was just after branching stable/14. Today I tried to build kernel from sources mounted over NFS and I ened with: # strings /usr/obj/usr/src/amd64.amd64/sys/BSDONDELL/kernel | grep 14.0-STABLE @(#)FreeBSD 14.0-STABLE #6 -dirty: Tue Nov 7 14:04:35 CET 2023 FreeBSD 14.0-STABLE #6 -dirty: Tue Nov 7 14:04:35 CET 2023 14.0-STABLE the source repository is updated, consisted, but mounted read-only over NFS /usr/src# git status On branch stable/14 Your branch is up to date with 'origin/stable/14'. Untracked files: (use "git add <file>..." to include in what will be committed) sys/amd64/conf/BSDONDELL It took 2.53 seconds to enumerate untracked files. See 'git help status' for information on how to improve this. nothing added to commit but untracked files present (use "git add" to track) Any clues what could be wrong ? Does /usr/src/ require write permissions now ? -- Marek Zarychta
