We have discussed going with the USB stick route. However, what spurred this is because not only the OVERSIZED warning, but also because the images are merely copies of the 20220322 image and are not updating upon build. I thought this was due to the oversize warning. Either way, this is very concerning as we can't correctly test the builds due to a resolved bug involving automount conflicting with Calamares. > > HOWEVER, and this is why I'm CCing the Release Team and ubuntu-devel@, > > there is another ISO format that works for DVD: ISO 13346, aka UDF.
