[Pkg-shadow-devel] Bug#249372: "Please enable login for GNU/Hurd": Can someone summarize this bug report?

[Nicolas François]

Hello,

This is a little bit related to this thread, and may help to find which
variables need to be set in login.defs.

Here is the (I hope complete list) of variables used by the shadow
utilities (I hope it is not in dead code), sorted by package/utility and
by variable.

I did not find any differences with or without the patch 404 (so this list
should be maintained after the re-PAMification).

I've made this list by checking which getdef_* calls were linked in the
utilities, and then by (quickly) checking wether these getdef_ were really
used. (So it may not be exact).

Kind Regards,
