NAME

freebsd-update – fetch and install binary updates to FreeBSD

CONTENTS

SYNOPSIS


freebsd-update [-b basedir] [-d workdir] [-f conffile] [-F] [-k KEY] [-r newrelease] [-s server] [-t address] [--not-running-from-cron] command ...

DESCRIPTION

The freebsd-update tool is used to fetch, install, and rollback binary updates to the FreeBSD base system. Note that updates are only available if they are being built for the FreeBSD release and architecture being used; in particular, the FreeBSD Security Team only builds updates for releases shipped in binary form by the FreeBSD Release Engineering Team, e.g., FreeBSD 10.3-RELEASE and FreeBSD 11.0-RELEASE, but not FreeBSD 10.3-STABLE or FreeBSD 12-CURRENT.

OPTIONS

The following options are supported:
-b basedir
  Operate on a system mounted at basedir. (default: /, or as given in the configuration file.)
-d workdir
  Store working files in workdir. (default: /var/db/freebsd-update/, or as given in the configuration file.)
-f conffile
  Read configuration options from conffile. (default: /etc/freebsd-update.conf)
-F Force Cm to proceed where it normally would not, such as an unfinished upgrade
-k KEY Trust an RSA key with SHA256 of KEY. (default: read value from configuration file.)
-r newrelease
  Specify the new release to which freebsd-update should upgrade (upgrade command only).
-s server
  Fetch files from the specified server or server pool. (default: read value from configuration file.)
-t address
  Mail output of cron command, if any, to address. (default: root, or as given in the configuration file.)
--not-running-from-cron
  Force Cm to proceed when there is no controlling tty. This is for use by automated scripts and orchestration tools. Please do not run Cm from crontab or similar using this flag, see: Cm
--currently-running release
  Do not detect the currently-running release; instead, assume that the system is running the specified release. This is most likely to be useful when upgrading jails.

COMMANDS

The command can be any one of the following:
fetch Based on the currently installed world and the configuration options set, fetch all available binary updates.
cron Sleep a random amount of time between 1 and 3600 seconds, then download updates as if the fetch command was used. If updates are downloaded, an email will be sent (to root or a different address if specified via the -t option or in the configuration file). As the name suggests, this command is designed for running from cron(8); the random delay serves to minimize the probability that a large number of machines will simultaneously attempt to fetch updates.
upgrade Fetch files necessary for upgrading to a new release. Before using this command, make sure that you read the announcement and release notes for the new release in case there are any special steps needed for upgrading. Note that this command may require up to 500 MB of space in workdir depending on which components of the FreeBSD base system are installed.
install Install the most recently fetched updates or upgrade.
rollback
  Uninstall the most recently installed updates.
IDS Compare the system against a "known good" index of the installed release.

TIPS

FILES
