If you use #pmbootstrap when working with #postmarketOS, I'd welcome any testing results for migrating your work directory with . Just checkout the branch and try to run $ pmbootstrap init and it'll prompt you for whether to migrate. Even successful test results are nice to see as they build confidence in that it works properly!
Glad to finally have #Zstd compression enabled for #AlpineLinux's linux-firmware package exactly half a year (minus a few hours) after originally opening the merge request during our post-Fosdem #postmarketOS hackathon! If you're running Alpine (or postmarketOS) and have all linux-firmware packages installed, the on-disk space will go down from around a gigabyte to around half a gigabyte or so, which I think is pretty decent.
