What kind of hacks are you talking about exactly?

Are you sure that this only affects the qemu cdrom? Shouldn't we provide
a simple workaround that catches all CD drives, no matter what kind of
weird bugs there might be?

This should be fixed in the kernel, but I have no idea if and when a fix
will be written and/or accepted.

Can you summarize what exactly -T split does?

Also, there is the overlay: We used to have a separate overlay for each
architecture, is that still necessary? If we add "Architecture = auto"
to pacman.conf and use $arch in mirrorlist (is that already done?), it
seems we can use the same overlay for both architectures.
