Understanding NvPCRs in systemd v262

systemd answers TPM PCR scarcity with additional PCR-like registers allocated in the TPM’s NV memory, with an anchoring design that was reworked in v262. In this hands-on deep dive, we rebuild a systemd NvPCR from scratch against a software TPM, picking up the required TPM concepts along the way, and analyze why the design is secure. Why can’t systemd get enough of those PCRs? Many of systemd’s security features rely on TPM PCR measurements: Passwordless full disk encryption can unlock disks aut

After almost two years being quiet, we are back. We have now:

  • An own OCI registry at https://hub.nspawn.org with everything built using mkosi
  • A new website at https://nspawn.org with up to date documentation.
  • A new CLI client that does support our registry (or any OCI registry), DockerHub, and more. It supports entrypoints, search, pull, exec, and more docker-ish commands. It supports build too and invokes mkosi.

All the details on https://blog.nspawn.org/posts/nspawn-comeback-an-oci-hub-new-images-and-nspawn-1-0-0/

Ya el panorama pintaba difícil en cuanto a opciones de sistemas operativos cuando irrumpió #systemd, pero ahora se suma la mal llamada #IA a acotar aún más esas pocas opciones que había... Tan cerca y tan lejos a la vez de esa época donde había cientos o miles de sistemas operativos para elegir... A este paso tendré que volverme un experto y usar #Gentoo o pasarme a #BSD de la mano de #NetBSD...

I noticed that signing in to Mastodon using 2FA didn't reliably work. Turns out my system clock was ~30 seconds behind that of the actual time (currently GMT +1 for me).

On Linux distributions that have systemd, systemd apparently synchronises your system time with a time server automatically. However, I use Devuan (i.e. Debian but without systemd) so I had to do it manually.

I used htpdate to set the time to a UK time server on pool.ntp.org like this:

sudo htpdate uk.pool.ntp.org

No need to reboot. It's now accurate to GMT+1 to within about half a second. :)

Liebes #Fediverse und vor allem liebe #mastoadmin Gruppe. Wie ist euer aktueller Stand zu #SideKiq und deren Worker und Queues. Früher hatte man die ja auf ggf. mehrere laufende #SystemD Units aufgeteilt, ich meine aber das dies nicht mehr aktuell ist und keinen Vorteil bringen sollte. Aktuell sieht es bei uns halt wie folgt aus und ich frage, mich warum ich ihn nicht dazu bekomme mehr zu machen. DB_POOL:140 worker: 128 queues: default, 20 push, 9 ingress, 30 mailers, 3 #anoxinon Tipps?

Unranked, systemd, crawls

There’s been some changes to Marginalia Search: Migrated to systemd from docker New unranked query endpoint Wide domains got their own index for faster crawls In brief, this has removed a lot of operational headaches, reduced expensive queries leaving more computational power for the rest, and cut crawl times in half. Let’s tackle them in some order. We have docker at home The system has been migrated off docker compose, and onto bare systemd in production. This has been successful, and solved a
