[Bug 1917148] Re: ps version is UNKNOWN in procps 2:3.3.16-1ubuntu2

[Eric Desrochers]

I'll be reviewing the change with my colleague Kellen.

In the meanwhile ...
What is the concern/impact behind not having the version available in ps ? (Outside it should output/report it) ?

The version can be found in the package version (dpkg -l procps)

Is it for integrity purposes in order to make sure the ps binary in
place really comes from that given procps package ? If it is the case,
making --version works won't help much as an integrity check. There are
other approaches that can be used to achieve this goal such as 'dpkg '--
verify' and '--audit'

To summarize, I'm trying to find the rationale behind it to clearly
document the bug when we'll reach the SRU approval/justification.
