[atomic-devel] Q: Detecting Container-ness is still container=something?

[Chris Evich <cevich redhat com>]

All,

Looking for some advice re: a tooling bug.  The problem (bug) has to do 
with sosreport incorrectly determining whether or not it's not running 
w/in a SPC container.  The context is always going to be from within an 
SPC, on an RHEL/Fedora/CentOS Atomic host.  Sosreport needs to be useful 
in helping diagnosing __host__ problems, with container data-collection 
being a secondary use-case.

To address detection, we're aware of 'container=docker', and 'HOST', but 
both seem quite flimsy.  We've also considered a check based on 
/proc/1/root.  We also understand "container-ness" in some cases may be 
intentionally obscured for security/isolation purposes.

For the general case (no security issue), in RHEL/Fedora/Centos Atomic 
Host, within a SPC context, is checking the container env. var still the 
preferred method?

Thanks in advance for any advice on this.
