Distro

crypto-config:

  • switched to the “metadata.json” file as per-spec (rather than the previous hack)
  • started experimenting with a rewrite in Rust (the language choice is complicated due to trying to keep size small
  • I need to publish the spec; it’s basically ready if copy-paste works fine between google docs and discourse

This week I mostly looked at the nbd-client autopkgtests across Noble, Oracular and Plucky. All the MIRs from the previous week have comments and I am resolving them (nlohmann-json3 and raspi-utils will go through a security review). The nbdclient MPs are being reviewed by seth-arnold:

libpisp symbols: needs information Merge into ubuntu/devel : ubuntu/devel : lp:~r41k0u/ubuntu/+source/libpisp : Git : Code : libpisp package : Ubuntu

Misc: visa documentation, Pi meetings
