How to apply patches on OpenBSD system/kernel and packages easily

To apply patches on an OpenBSD system, you can use the “syspatch” command. This command updates the operating system and packages with the latest security patches. To use it, run the following command as root:

# syspatch

If there are no patches available, you will see the message “Your system is up to date.” If there are patches available, you will see a list of the patches that will be applied. You will be prompted to confirm the installation of each patch.

Alternatively, you can use the “sysmerge” command to update the operating system and packages to a newer release. This command is used to upgrade between minor releases of OpenBSD. For example, to upgrade from OpenBSD 6. (fujifilm-x) 9 to 6.10:

# sysmerge

This will download the necessary files and perform the upgrade. You will be prompted for confirmation at each step of the process.
