bectl: log modifying functions to zpool history

2026-01-20T04:08:09Z

Modeled directly after the method used by the zfs/zpool commands: flag commands with a "please log me" flag, and when there, reconstruct the command line. On success, call the library function to add it to the log.

libbe: don't hardcode /tmp

Respect $TMPDIR if it's set, fallback to _PATH_TMP (not hardcoded /tmp) if it's not. Bump .Dd after recent commits. Reviewed by: rcm (cherry picked from commit 2f11393fee4d60d38634a261edf9aa9fea39c75c)

libbe: attempt to remove autocreated mountpoints at unmount time

2025-04-26T03:23:55Z

We use a be_mount.XXXX pattern to mkdtemp(3) when creating these, which seems reasonably unique enough to just continue using that. Record the mountpoint of the root dataset and check the dirname of that for the auto-creation trait. There's no sense in this bubbling up an error to callers, so we'll just ignore an error for now.

libbe(3): document be_snapshot()

loader: zfs should support bootonce an nextboot

2020-09-21T09:01:10Z

bootonce feature is temporary, one time boot, activated by "bectl activate -t BE", "bectl activate -T BE" will reset the bootonce flag. By default, the bootonce setting is reset on attempt to boot and the next boot will use previously active BE. By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will be set permanently active. bootonce dataset name is recorded in boot pool labels, bootenv area. in case of nextboot, the nextboot_enable boolean variable is recorded in freebsd:nvstore nvlist, also stored in boot pool label bootenv area. On boot, the loader will process /boot/nextboot.conf if nextboot_enable is "YES", and will set nextboot_enable to "NO", preventing /boot/nextboot.conf processing on next boot. bootonce and nextboot features are usable in both UEFI and BIOS boot. To use bootonce/nextboot features, the boot loader needs to be updated on disk; if loader.efi is stored on ESP, then ESP needs to be updated and for BIOS boot, stage2 (zfsboot or gptzfsboot) needs to be updated (gpart or other tools). At this time, only lua loader is updated. Sponsored by: Netflix, Klara Inc. Differential Revision: https://reviews.freebsd.org/D25512
