NAME

sysupgrade — upgrade system to the next release or a new snapshot

SYNOPSIS

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:

-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.
