Hi @ralimi, thanks for the PR. Do you have an aarch64 platform by hand and could provide facts to https://github.com/camptocamp/facterdb ? Or as an alternative, could you mock this architecture in our current tests so we can ensure that everything still compiles?

Thanks for the quick feedback!

I looked briefly at contributing to facterdb and, if I understand correctly, the way to get things included as part of the standard release is to have a vagrant box. From https://app.vagrantup.com/boxes/search?utf8=%E2%9C%93&sort=downloads&provider=&q=arm64 (I did an equivalent search for aarch64 too), it doesn't seem like there is an appealing/regularly-maintained option. Let me know if I'm misunderstanding things there.

I'll dig around the unit tests to see where best to mock this. A quick search (e.g., for armv7l) didn't yield examples. Let me know if I'm missing something there.

you can have a look at https://github.com/camptocamp/facterdb/blob/master/facts/get_facts.sh. It's basically enough to run facter -j and put the output into a file. That's also the way I used to get the archlinux facts that are in facterdb.

Hi @bastelfreak, what are the next steps here?

So far:

• I've got this running successfully in my local setup.
• Facts have be added to facterdb.

If I understand correctly, this wouldn't be used in tests until the next facterdb release. If that understanding is correct, what is the best thing to do before then?

Thanks for the work!
