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

Drop "All Rights Reserved" from all libbe/bectl files

2020-01-24T02:18:09Z

I sent out an e-mail on 2020/01/21 with a plan to do this to Kyle, Rob, and Wes; all parties have responded in the affirmative that it's OK to drop it from these files.

bectl(8): Add a "check" command

2019-09-11T13:27:10Z

This command simply returns 0 at the moment and explicitly takes no arguments. This should be used by utilities wanting to see if bectl can operate on the system they're running, or with a specific root (`bectl -r`). It may grow more checks than "will libbe successfully init" in the future, but for now this is enough as that checks for the dataset mounted at "/" and that it looks capable of being a BE root (e.g. it's not a top-level dataset) bectl commands can now specify if they want to be silent, and this will turn off libbe_print_on_error so they can control the output as needed. This is already used in `bectl check`, and may be turned on in the future for some other commands where libbe errors are better suppressed as the failure mode may be obvious.

bectl(8): implement sorting for 'bectl list' output

2019-09-04T13:59:06Z

Allow 'bectl list' to sort output by a given property name. The property name is passed in using a command-line flag, '-c' for ascending order and '-C' for descending order. The properties allowed to sort by are: - name (the default output, even if '-c' or '-C' are not used) - creation - origin - used - usedds - usedsnap - usedrefreserv The default output for 'bectl list' is now ascending alphabetical order of BE name. To sort by creation time from earliest to latest, the command would be 'bectl list -c creation' Submitted by: Rob Fairbanks Reviewed by: ler MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D20818

bectl(8): add description for create subcommand

2019-05-22T23:07:40Z

In commit r345845, a portion of documentation for the create subcommand was removed. Specifically, for creating a snapshot of an existing boot environment. bectl even has a test-case for this functionality. Removing the sub-command description was discussed in PR 235850. This patch brings back the second "create" description that was originally in place. Albeit, with a few wording/clarifying changes.
