In the article, Florian details the steps to modern OpenBSD dynamic host configuration, including interface configuration, name resolution, routing and more.
We also get an explanation of the various userland programs (most of them portable, some OpenBSD-specific) that make a modern OpenBSD laptop shine.
You can read the full piece here, Dynamic host configuration, please.

Bringing up the subject, Katie McMillan wrote in, saying
I am looking for Canadian OpenBSD contributors for a Q&A, and they haven't been easy to find. You would think that they would be, considering that the person who started the project is from Canada, but it hasn't been. Does this mean that OpenBSD is dead in Canada?

Theo de Raadt (deraadt@) posted to tech@ a status report (and 2 test programs) regarding execute-only (xonly). The report begins:
We've made good progress in the xonly effort so here's a small summary. architectures crossed over completely arm64 - X bit without implied R in mmu riscv64 - X bit without implied R in mmu amd64 - using hardware 'PKU' feature powerpc64 - using feature similar to PKU hppa - using gateway featureAs part of her efforts in developing patches for the console (many of which have been committed recently), Crystal Kolipe created some patches for taking screenshots of the OpenBSD console.
She wrote an in depth article, Coding new ioctls to produce screendumps from the console, about her work.
We will look forward to further development and refinement on this.
Support for execute-only (xonly) code (on which we reported earlier) has been committed to -current by Theo de Raadt (deraadt@).
