@efahl - I noticed unusually high loading on the ASU/Firmware Selector servers with the release of 25.12.2. Obviously the servers are going to be under relatively heavy demand immediately after a release, but I think that the servers are being loaded unnecessarily.
Specifically, I found that even a completely stock device will send a build request to the firmware selector when using ASU/OWUT.
Take a device running the standard/default image of 25.12.1. In this scenario, there are no packages added to the image, nor are any installed post-flash. We can even use a completely (reset to) default configuration (although this is not all that relevant here).
OWUT will inform the user that there is a new version (25.12.2 just came out)... clicking through and attempting to get an update will send a request to the ASU builders and will (attempt) to queue up a build.
Given the new integration of OWUT/ASU into the standard OpenWrt 25.12 images, even users with a totally default configuration will end up queuing new customized images, despite the fact that it is clearly not needed. The standard download of the new version (25.12.2 in this case) without customization is all that is necessary.
With that in mind, it seems extremely wasteful of the limited ASU server resources to send all upgrade requests for custom builds. This causes long queues for users who do need custom builds, and even seems to be causing them to fail at the moment, after potentially an hour or more in said queue.
Is there a way that the OWUT/ASU system could detect the fact that there is no need to request/build a custom image? I could imagine this being done on-device by comparing the currently installed packages against the manifest of the default image. Or, similarly, the ASU servers could do the same thing as a triage step (if installed packages == default manifest, deliver standard image for download; else enter queue for custom build).
NOTE: I just moved this from the Firmware Selector thread to this (OWUT thread) as it's probably more appropriate here.
