Going to keep it very brief this week because I'm once again recovering
from a wisdom teeth extraction (the last one!).

• Yureka's libbpf fix[1] has been applied upstream, and she's now
working on exposing vhost-user-net devices from her userspace router.
• Demi has been doing some exploratory work on using systemd on the
Spectrum host system[2]. We want to evaluate whether the extra
complexity would be justified to get access to its extensive
sandboxing features.
• Apart from recovering, I did a routine test build with a new Nixpkgs,
and then spent a while bisecting a kernel regression that broke
virtio-gpu[3] (which it turned out had already been discovered and
reverted, but my report at least got it tracked by regzbot as well).

We also did some work sorting out the new funding.
