Demonstrate live reload without watchexec

[joshuatcasey]

It appears that web servers will reload without watchexec

[ForestEckhardt]

What is the purpose of adding these tests? I understand that it is something that can work but what are we trying to do?

[joshuatcasey]

@ForestEckhardt This was really a technical exercise to see if it would work and it's saved off as a PR.

We had a discussion yesterday at standup about trying to capture all of the context around webservers (both here and in the PHP language) and reloading on a single issue and making a decision there.

I guess my question is what should I be doing about this PR then? Are we merging it as is or is there still a conversation happening?

[joshuatcasey]

Let's leave it open for now. I'll say status/blocked on an overall decision.

I've proposed in paketo-buildpacks/php-start#37 that the PHP language family explicitly support live reload of served files without additional configuration such as BP_LIVE_RELOAD_ENABLED=true.

I propose that the web-servers adopt a similar approach:

• Let nginx or httpd reload served files without requiring additional configuration since this happens anyways and is likely more responsive than reloading the process
• Document that some configuration changes can result in reloading the nginx or httpd process, specifically file changes (not env var changes).
