OpenBSD Upgrade
================
Today I spent some time upgrading my home router.  It was still
running OpenBSD 7.1.  I know, it's neglect on my part.  Anyway,
I thought I will need to reinstall the whole thing which I was
reluctant to do.

Thanks to OpenBSD Webzine I found the new `sysupgrade` script
only recently commited by Theo De Raadt which allows jumping
from some early version to the newly released 7.6.

https://webzine.puffy.cafe/issue-18.html
https://cvsweb.openbsd.org/src/usr.sbin/sysupgrade/sysupgrade.sh?rev=1.55&content-type=text/x-cvsweb-markup
https://cvsweb.openbsd.org/cgi-bin/cvsweb/~checkout~/src/usr.sbin/sysupgrade/sysupgrade.sh?rev=1.55&content-type=text/plain

I uploaded the script to my router, changed `/usr/installurl`
to a mirror that still contains version 7.2 and kept running
the script several times to upgrade my machine to the new
release.

Worked like a charm!

My gratitude to Theo De Raadt for the new `sysupgrade.sh` and
Solene for making it known.
