But noexec:
mount | grep run
tmpfs on /run type tmpfs (rw,nosuid,nodev,noexec,relatime,size=203112k,mode=755)
On install the unit is enabled (postinst has the dusual dh_installsystemd
snippet), but sadly it stays disabled. Even after reboot, despite the enabled
config it stayed disabled.
To be clear once started (manually for now) it works fine
$ sudo systemctl start run-qemu.mount
$ systemctl status run-qemu.mount

$ mount | grep run

And a reinstall now places files in there as it did before:

Seems I'm cursed with dh_installsystemd magice recently, maybe the
.mount behaves differently in dh*. In any case the postinst really has
no start section for it, so it can't work yet.
