* doc/contributing.texi (Running Guix Before It Is Installed): Move
'./pre-inst-env guix-daemon' example after the mention of GUILE_LOAD_PATH &
co, because running the daemon from the checkout frequently trips new users.
Additionally clarify that sudo must be setuid.

Beware the dot above. You could write

  E.g.@: if you…

or

  E.g., if you…
                  

instead.

Looks good, but you should mention that, before running the daemon that way, the one running on the system must be stopped (herd stop guix-daemon or whatever init system is installed).

I am not native speaker but last time I have checked the rule for
Latin abbreviation, if I remember well, it says: it depends. :-)
In general, the style guides says always a comma before, i.e. like that.
However, the comma after depends on U.S. vs U.K.:
  - U.S., i.e., comma after the abbreviation;
  - U.K., i.e. no command after the abbreviation.


Cheers,
simon

I was talking about Texinfo syntax, where "E.g. if" is misleading. Sorry
if that was not clear.

Ludovic today pushed a changed very similar in commit
9022861dc028e99fab930721fe991a682c497bbb, obsoleting this one.

Closing.

Thank you,
