+
+# You *must* set USERADD_PARAM and/or GROUPADD_PARAM when
+# you inherit useradd.
+
+# USERADD_PARAM specifies command line options to pass to the
+# useradd command. Multiple users can be created by separating
+# the commands with a semicolon. Here we'll create two users,
+# user1 and user2:
+USERADD_PARAM_${PN} = "-u 1200 -d /home/user1 -r -s /bin/bash user1; -u 1201 -d /home/user2 -r -s /bin/bash user2"
+
+# user3 will be managed in the useradd-example-user3 pacakge:
+USERADD_PARAM_${PN}-user3 = "-u 1202 -d /home/user3 -r -s /bin/bash user3"
+
+# GROUPADD_PARAM works the same way, which you set to the options
+# you'd normally pass to the groupadd command. This will create
+# groups group1 and group2:
+GROUPADD_PARAM_${PN} = "-g 880 group1; -g 890 group2"
+
+# Likewise, we'll manage group3 in the useradd-example-user3 package:
+GROUPADD_PARAM_${PN}-user3 = "-g 900 group3"
