Comment # 6 on bug 1181018 from Kurt Garloff

What does NOT work:
When I try to just mount it (mount /dev/fd0 /mnt), it will reproducibly fail
with the bogus absent medium.

So, here's my theory:
* There is a medium change detection (maybe qemu does it on purpose)
* It should be acknowledged on the first access
* Reading from the device does clear it
* Mounting does not
* This has been broken in kernels (or qemu?) for quite some time
* The fact that cloud-init-20.2 does straight away try to mount the floppy
without any prior inspection triggers this

Obviously, the theory needs validation
* I'll retry with 5.3.18-lp152-50 kernel
* I'll have a look at the older cloud-init code
