The qemu-ga binary is already moved to a separate
output but still depends on qemu, adding about
600MiB to it's closure.
The command "strings qemu-ga" reveals that something
like
/nix/store/bqgpvv5qrpb741swczqk3lrdm5gzaqx2-qemu-host-cpu-only-6.2.0/bin
is contained, causing this false positive. So use
remove-references-to to reduce the closure to about
600KiB.
