manage base system binary patches

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:
-c- List available patches; suitable for
cron(8).
-l- List installed patches.
-R- Revert all patches.
-r- Revert the most recently installed patch.
- /etc/installurl
- OpenBSD mirror top-level URL for fetching
patches.
- /var/syspatch/*
- Directories containing the rollback tarball and original signed
diff(1) of installed
patches.
syspatch first appeared in OpenBSD
6.1.
syspatch is designed to work solely on official
OpenBSD releases.
