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.
