It's the "qemu-server" repository, not "qemu".

Can this cause issues for a brief time during upgrade/unpacking, i.e.
A) if the old QemuServer.pm is still loaded while the scripts get
removed from its old location (or to be more precise, a QEMU process
with the old parameter is started at that time)
B) if the new QemuServer.pm gets loaded before the scripts are extracted
to their new location (or to be more precise, a QEMU process with the
new parameter is started at that time)
?
Is there something preventing those from happening? Otherwise, we might
need to ship the scripts to both locations until the next major release
and drop them from the old location only then.
