New blog post introducing the WIP Duranium project (immutable postmarketOS), some of its major features, and explaining why some design decisions were made.  

> Either the new image works, or the system falls back to the previous one automatically. No partially-applied state. No debugging audio when you need to make a phone call and no fussing with a broken web browser when you just want to doomscroll cat photos. It also means developers can reproduce the exact state of a user's device, making it much easier to track down and fix issues.

@postmarketOS how does "No debugging audio when you need to make a phone call and no fussing with a broken web browser" follow from "the system boots successfully"? The system may boot successfully with a broken audio and/or a broken web browser. I'm curious and didn't find it in the blog post

the idea is that faults like this can be discovered before an update is applied as it's much easier to replicate and test the images, and a partial-upgrade state (which might break something like audio) is entirely avoided as updates are effectively atomic

@alexia @postmarketOS broken audio makes me think primarily about audio being broken on particular hardware due to an unaccounted edge case. Doesn't that mean that you can test an image on some hardware or even a few different phones, but still miss it being broken on some particular other audio chip?

perhaps but the aim of the project is moreso to prevent situations in which audio was working and then broke after an update without an easy recovery path.

@alexia @postmarketOS but this is still possible, as I just described?
