Provide pam_passwdqc setup example for Linux #19
Description
In PLATFORMS, we happen to have more specific instructions for some non-Linux systems than we do for Linux. We should similarly add instructions or/and example(s) for common Linux distributions.
Our current:
Most modern Linux distributions use Linux-PAM with a password changing
module which understands "use_authtok". Thus, you may choose which
module prompts for the old password, things should work either way.
assumes that the reader knows where and how to add pam_passwdqc to the PAM stack, and only needs that specific configuration detail above - but many people reading that don't have such knowledge.
For FreeBSD/DragonFly and OpenBSD, we refer to specific pathnames to make edits to. For many people, that's much more helpful.
For Solaris, we refer to a wiki page, which has instructions and examples. That's also more helpful (than what we have for Linux), although we could want to have our documentation in here more self-contained.
