NAME #
sysupgrade - upgrade system to the next release or a new snapshot
SYNOPSIS #
sysupgrade [-fkn] [-r | -s] [-b base-directory] [installurl]
DESCRIPTION #
sysupgrade is a utility to upgrade OpenBSD to the next release or a new snapshot if available.
sysupgrade downloads the necessary files to /home/_sysupgrade, verifies them with signify(1), and copies bsd.rd to /bsd.upgrade.
sysupgrade by default then reboots the system. The bootloader will automatically choose /bsd.upgrade, triggering a one-shot upgrade using the files in /home/_sysupgrade.
The options are as follows:
-b base-directory
Download files to base-directory/_sysupgrade instead of /home/_sysupgrade.
-f
Force an already applied upgrade. The default is to upgrade to latest snapshot only if available. This option has no effect on releases.
-k
Keep the files in /home/_sysupgrade. By default they will be deleted after the upgrade.
-n
Fetch and verify the files and create /bsd.upgrade but do not reboot.
-r
Upgrade to the next release. This is the default if the system is currently running a release.
-s
Upgrade to a snapshot. This is the default if the system is currently running a snapshot.
See upgrade.site(5) for how to customize the upgrade process.
