</span><p dir="ltr">Longer answer:</p>
<p dir="ltr">I was not closing the discussion as it's something that will be decided by the group. but having ps in a container means that we're treating it as a virtual machine.<br>
That's a huge change of the paradigm and not something we should encourage.</p>
<p dir="ltr">Moreover, the use case mentioned is not supported: PS is here used to retrieve process PID in a SysV init scripts, something we're supposed not to support anymore.<br>
It may hide another issue but putting back ps is not the right thing to do.<br>
Smarter effort would be making ps container-aware on the host if you need advanced process management.</p>
<p dir="ltr">That's definitely not consistent with the Atomic host story, too.</p>
