The branch main has been updated by jlduran: URL: https://cgit.FreeBSD.org/src/commit/?id=e5579f98c02ff64b0c305f6731c3557ba69c2d25 commit e5579f98c02ff64b0c305f6731c3557ba69c2d25 Author: Jose Luis Duran <jlduran@FreeBSD.org> AuthorDate: 2024-11-08 18:13:48 +0000 Commit: Jose Luis Duran <jlduran@FreeBSD.org> CommitDate: 2024-11-16 06:55:57 +0000 nanobsd: Avoid read-only file system warnings The default setting of some loader or rc variables generate warnings because the file system is read-only: Set the following options to avoid printing these warnings: /boot/defaults/loader.conf: - hostuuid_load="NO" to disable loading /etc/hostid early at boot time - entropy_cache_load="NO" to disable loading cached entropy at boot time - kern.random.initial_seeding.disable_bypass_warnings="1" to disable logging a warning if the 'bypass_before_seeding' knob is enabled (enabled by default) and a request is submitted prior to initial seeding /etc/defaults/rc.conf: - kldxref_enable="NO" to disable building linker.hints files with kldxref(8) - entropy_boot_file="NO" to disable very early (used at early boot-time) entropy caching through reboots - entropy_dir="NO" to disable caching entropy via cron While here, move rc.conf options before sourcing vendor.conf, so they can be overridden.
