I actually think you are very qualified, because you know what is
missing from the current text.

It would be useful if you could at least point out what information
should be added to the current text to make it more useful to your use
case.  Someone else could then convert that to an actual patch.

Thanks.

Any other missing pieces of information you'd like to be added?

Also, I don't think I understand clearly what exactly failed in your
case.  Did you have XDG_RUNTIME_DIR defined or didn't you?  If you
did, what exactly caused the failure to find the socket?

Thanks.
