The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=c475e61f66fe8fe939e18ec7821c2340569f3271 commit c475e61f66fe8fe939e18ec7821c2340569f3271 Author: Stéphane Rochoy <stephane.rochoy@stormshield.eu> AuthorDate: 2023-12-21 14:05:58 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2024-02-02 19:04:57 +0000 stand/lua: always allow overriding with local config files Loader now also read configuration files listed in local_loader_conf_files. Files listed here are the last ones read. And /boot/loader.conf.local was moved from loader_conf_files to local_loader_conf_files leaving only loader.conf and device.hints in loader_conf_files by default. The idea is to ensure local_loader_conf_files, i.e., /boot/loader.conf.local, can always be used to override other user defined settings. So the sequencing is now as follow: 1. Bootstrap: /boot/defaults/loader.conf 2. Read loader_conf_files files: /boot/device.hints /boot/loader.conf 3. Read loader_conf_dirs files: /boot/loader.conf.d/*.conf 4. And finally, rread local_loader_conf_files files: /boot/loader.conf.local Reviewed by: imp, kevans Pull Request: https://github.com/freebsd/freebsd-src/pull/759 --- UPDATING | 21 +++++++++++++++++++++ stand/defaults/loader.conf | 3 ++- stand/defaults/loader.conf.5 | 32 ++++++++++++++++++++++++++++---- stand/lua/config.lua | 15 ++++++++++++--- stand/lua/config.lua.8 | 8 ++++++-- 5 files changed, 69 insertions(+), 10 deletions(-) diff --git a/UPDATING b/UPDATING index 14fae1eb0656..33bae2a42b9d 100644 --- a/UPDATING +++ b/UPDATING @@ -27,6 +27,27 @@ NOTE TO PEOPLE WHO THINK THAT FreeBSD 15.x IS SLOW: world, or to merely disable the most expensive debugging functionality at runtime, run "ln -s 'abort:false,junk:false' /etc/malloc.conf".) +20240202: + Loader now also read configuration files listed in local_loader_conf_files. + Files listed here are the last ones read.
