syspatch is a utility to fetch, verify,
install and revert OpenBSD binary patches.
When run without any options,
syspatch will apply
all missing patches,
creating a rollback tarball containing the files it is about to replace,
then extracting and installing all files contained in the syspatch tarball.
Patches are cumulative and as such it is not possible to install only a
subset of them.
The options are as follows:
- List available patches; suitable for cron(8).
- List installed patches.
- Revert all patches.
- Revert the most recently installed patch.
- OpenBSD mirror top-level URL for fetching patches.
- Directories containing the rollback tarball and original signed diff(1) of installed patches.
