From e98e98ce65cf9ffdef29462310a622ffddd1412b Mon Sep 17 00:00:00 2001 From: Peter Kjellerstedt Date: Sat, 19 Dec 2015 00:53:50 +0100 Subject: useradd-staticids.bbclass: Simplify the logic for when to add groups The original code was near impossible to follow, and missed a couple of cases. For example, if one added the following line to the passwd file specified in USERADD_UID_TABLES: foobar:x:12345:nogroup::/:/bin/sh and then specified the user as: USERADD_PARAM_${PN} = "--system foobar" one would then assume that the foobar user would be created with the primary group set to nogroup. However, it was not (the primary group would be foobar), and the only way to get it correct was to explicitly add --gid nogroup to the USERADD_PARAM_${PN}.
