Description Radek Steiger 2016-03-17 13:06:57 UTC 
PCS daemon supports reading several various environmental variables that are usually set via initscript or systemd through /etc/sysconfig/pcsd, but are not documented anywhere at this point.

So far we expose following ones in /etc/sysconfig/pcsd and should mention them in man pages:

PCSD_DEBUG
RACK_ENV
DISABLE_GUI

Ideally, we should provide a general description of the supported ENV variables without being tied to /etc/sysconfig, because a user might want to set these in other ways (and also other distributions might use different approach than what we do in RHEL).

We might consider other ENV variables that pcsd already understands, but most of them are for internal use only.

To articulate that aloud, also the environment variables the underlying
components are known to honor should be mentioned.

See, for instance, https_proxy and no_proxy, just as these get documented
in WGET(1) ... related [bug 1315627].
