Awesome work! Noticed that the metadata.json still needs to be updated. Something like the following.

    {
      "operatingsystem": "AIX",
      "operatingsystemrelease": [
        "6.1",
        "7.1",
        "7.2"
      ]
    }

Finally =)

Hi @feltra, thanks for all the updates! Could you also add the correct versions for AIX?
It would be really really awesome, if you could contribute AIX facts to the facterdb project:
https://github.com/camptocamp/facterdb

[feltra]

I will have a look.
Thanks

facter operatingsystemrelease returns 6100 instead of 6.1 ?

[feltra]

{name => AIX, family => AIX, release => {major => 6100-09-11-1810, full => 6100-09-11-1810}

[feltra]

I would keep this with family only and then handle the releases.

[feltra]

The return from operatingsystem release is 6100-09-11-1810..

[bastelfreak]

hrm this is pretty crappy from facter :(
@ghoneycutt do you think we should keep the current version of the metadata or update it to the actual value from facter?

[feltra]

I see for gentoo we don't care for release as well..

[bastelfreak]

We don't care for the versions on Gentoo and Archlinux because those are rolling release distributions. For everything else we have to care about it. Based on this data, the facts are mocked during the tests (and some other stuff).

[ghoneycutt]

I copy/pasted above from puppetlabs/stdlib. Suggest we use that format since that's what they use.

[bastelfreak]

sounds good. IMO we can merge this as soon as we get travis green.

[ghoneycutt]

A quick sampling of the Forge also shows using 'X.Y' format

[bastelfreak]

@feltra can you take a look at the failing travis jobs?

[bastelfreak]

thanks!

[bastelfreak]

@feltra please also think about adding the facts to https://github.com/camptocamp/facterdb <3
