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 |

# $FreeBSD$ This directory is for tools. A tool is something which is sometimes useful, and doesn't fit any of the other categories. Please make a subdir per program, and add a brief description to this file. ansify Convert K&R-style function definitions to ANSI style ath Tools specific to the Atheros 802.11 support cfi Common Flash Interface (CFI) tool commitsdb A tool for reconstructing commit history using md5 checksums of the commit logs. crypto Test and exercise tools related to the crypto framework cxgbetool A tool for the cxgbe(4) driver. cxgbtool A tool for the cxgb(4) driver. drm Tools specific to the DRM/KMS device drivers. editing Editor modes and the like to help editing FreeBSD code. epfe Extract printing filter examples from printing.sgml. ether_reflect An Ethernet packet reflector for low level testing. find-sb Scan a disk for possible filesystem superblocks. gdb_regofs A simple tool that prints out a register offset table for mapping gdb(1) register numbers to struct reg and struct fpreg offsets. The tool is useful on selected platforms only. genericize Turn a kernel config into something that can more easily be diffed against the appropriate GENERIC. git Tools to simplify the use of git by committers. hcomp Compress header files by removing comments and whitespace. html-mv Rename HTML generated filenames to human readable filenames. ifinfo Uses the interface MIB to print out all the information an interface exports in an ugly form. indent_wrapper Tool for style(9) checking SVN/GIT patches. intel-ucode-split Tool to split Intel microcode into individual files. iso Tool to compare the iso3166 and iso639 files in /usr/share/misc with the data from the master sites. iwi Tools specific to the Intel PRO/Wireless 2200BG/2225BG/2915ABG support. kdrv KernelDriver; add/list/remove third-party kernel driver source to/in/from a kernel source tree. kernelcruft Shellscript to find orphaned *.c files in /sys kerninclude Shellscript to find unused #includes in the kernel. kernxref Shellscript to cross reference symbols in the LINT kernel. kttcp An in-kernel version of the ttcp network performance tool man Scripts useful for working on man pages. mctest A multicast test program mid Create a Message-ID database for mailing lists. mwl Tools specific to the Marvell 88W8363 support ncpus Count the number of processors netmap Test applications for netmap(4) notescheck Check for missing devices and options in NOTES files. npe Tools specific to the Intel IXP4XXX NPE device pciid Generate src/share/misc/pci_vendors. pciroms A tool for dumping PCI ROM images. WARNING: alpha quality. pirtool A tool for dumping the $PIR table on i386 machines at runtime. portsinfo Generate list of new ports for last two weeks. scsi-defects Get at the primary or grown defect list of a SCSI disk. sysdoc Build a manual page with available sysctls for a specific kernel configuration. tinybsd Script to build FreeBSD embedded systems. track Track the progress of a world / kernel build vimage An interim utility for managing the virtualized network stack infrastructure. vop_table Generates a HTML document that shows all the VOP's in the kernel. whereintheworld Summarizes "make world" output.
