I don't use /etc/releases but /etc/os-release. There is no mapping
involved. If a distribution has no /etc/os-release or a messed up
/etc/os-release, then it needs to be fixed by the distribution. It's a
common standard and all relevant distributions support this standard.

RHEL has ID=rhel and no ID_LIKE -> ipaplatform.rhel

Fedora has ID=fedora and no ID_LIKE -> ipaplatform.fedora

CentOS has ID=centos and ID_LIKE="rhel fedora"
-> ipaplatform.rhel

Even my Raspberry has an /etc/os-release with ID=raspbian and
ID_LIKE=debian -> error, soon ipaplatform.debian

My proposal does not affect distribution packaging (rpm, deb) at all. It
is purely about Python packaging.

The client installer and client CLI code are already separated. The
Python wheels will only contain what 'python setup.py bdist_wheel' spits
out for ipaclient, ipalib, ipaplatform and ipapython. The 'ipa' CLI is
part of the ipaclient Python package.

For Ansible, testing etc. I need an arbitrary amount of config
*directories* and full control. I don't like the idea that the current
working directory affects how commands work. It has too many security
implications, e.g. we have to verify that the file belongs to the
current user. The check must be TOCTOU safe, too. Env vars are easier to
control, more secure and less fragile.
