Optimize SquashFS for currently supported use cases
We still optimize (sort) the SquashFS for bare metal DVD, while nowadays:
- ISO images are supported for VMs only.
- Everyone else should use the USB image.
So let’s instead optimize for bare metal USB sticks, i.e. the most common real-world use case. I doubt it’ll harm performance for VMs (an internal hard drive is very different from a bare metal DVD drive anyway).

Meh, this was done months ago, in commit:5273b9cf0545c6148275f3d547bab11d6e92c8e5, so we’re already supposed to optimize our SquashFS for USB drives. So I don’t understand why anonym asked me why we did not do this exact change, while he was releasing 4.0~beta1.
FTR, I’ve left the DVD burner part in
contribute/working_together/roles/release_manager because pretty often, no manual tester has the hardware for the “Boot on bare-metal from DVD” test, so it makes sense to ensure each RM is able to do that test as a fallback: assuming the RM reads the “In the beginning of your shift” section in the beginning of their shift, they have 6-9 weeks to find the needed hardware, while manual testers have much less time.
