exclude iso9660 disk in unused devices

[yueyuankun]

ISO version：Fedora-Server-dvd-aarch64-39-1.5.iso
use USB flash：dd if=Fedora-Server-dvd-aarch64-39-1.5.iso of=/dev/sdb

When I install the system on the hard drive, I select a custom partition and an unknown device appears in the spoke.

And I was refused to remove this device.

So let's exclude it from the unused device list.
After adding code:

[packit-as-a-service]

We were not able to find or create Copr project packit/rhinstaller-anaconda-5553 specified in the config with the following error:

Cannot create a new Copr project (owner=packit project=rhinstaller-anaconda-5553 chroots=['fedora-eln-x86_64', 'fedora-rawhide-x86_64']): Unable to connect to https://copr.fedorainfracloud.org/api_3/.

---

Please check your configuration for:

1. typos in owner and project name (groups need to be prefixed with @)
2. whether the project name doesn't contain not allowed characters (only letters, digits, underscores, dashes and dots must be used)
3. whether the project itself exists (Packit creates projects only in its own namespace)
4. whether Packit is allowed to build in your Copr project
5. whether your Copr project/group is not private

Is the purpose here to unmatch generally optical media?

Maybe using find_optical_media is the correct way?

@M4rtinK can you help with review please?

I'm thinking that perhaps what we are seeing it actually a bug - if the media is used to start the installation, there should be code that puts it to the list of protected devices, which I would expect will prevent it from showing up at all. So maybe that is broken ?

BTW, it looks like iso9660 might be not just on optical media but also bootable installation flash drives, once you dd an installation image on them.

I guess there could be also the case of a user having two bootable installation flash drives connected, one used to boot to the installation and then another one just connected. Then the second one could show up as iso9660 volume & the question is how should Anaconda handle it ? I guess provide an option to delete the partition iso9660?
