Logcheck devel - Feb 2016 - Bug#815114: Please whitelist sudo -g nogroup (not just sudo -u nobody)

Package: logcheck
Version: 1.3.17
Severity: wishlist
Tags: patch

Currently logcheck thinks

  "sudo -u nobody            pwd" is OK,
  "sudo           -g nogroup pwd" is scary; and
  "sudo -u nobody -g nogroup pwd" is scary.

IMO either these are all OK, or all scary --- probably the former.

Here is an (untested) patch against current logcheck;
I've been using a variation on oldoldstable systems for a while.
