NAME
sysupgrade —
upgrade system to the next release or a
new snapshot
SYNOPSIS
sysupgrade |
[-fkn] [-r |
-s] [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:
-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.
