re7f0fa1 rda7949d 201 201 <para>This parameter sets the beginning of the group numbers used in 202 202 the <filename>/etc/group</filename> file. The particular value 999 203 comes from the <parameter>--gid</parameter> parameter above. 204 You can modify it to anything you desire. Note that205 <command>useradd</command> will never reuse a UID or GID. If the 206 number identified in this parameter is used, it will use the next207 available number after this. Note also that if you don't have a208 group with an ID equal to this number on your system the first209 time you use <command>useradd</command>210 without the <parameter>-g</parameter> parameter, you'll get a message211 displayed on the terminal that says:212 <computeroutput>useradd: unknown GID 999</computeroutput>, although213 the account is correctly created. That is214 why we have earlier created the group215 <systemitem class="groupname">users</systemitem>216 with this group ID.</para>203 comes from the <parameter>--gid</parameter> parameter above.
