    30   <para>Throughout BLFS, many packages install programs that
    31   run as daemons or in some way should have a user or group name
    32   assigned.  Generally these names are used to map a user ID (uid) or group
    33   ID (gid) for system use.  Generally the specific uid or gid numbers used
    34   by these applications are not significant.  The exception of course, is
    35   that <systemitem class='username'>root</systemitem> has a uid and gid of 0
    36   (zero) that is indeed special.  The uid values are stored in
    37   <filename>/etc/passwd</filename> and the gid values
    38   are found in <filename>/etc/group</filename>.</para>

    40   <para>Customarily, Unix systems classify users and groups into two
    41   categories: system users and regular users.  The system users and groups are
    42   given low numbers and regular users and groups have numeric values greater
    43   than all the system values.  The cutoff for these numbers is found in two
    44   parameters in the <filename>/etc/login.defs</filename> configuration file.
    45   The default UID_MIN value is 1000 and the default GID_MIN value is 1000.  If a
    46   specific uid or gid value is not specified when creating a user with
    47   <command>useradd</command> or a group with <command>groupadd</command> the values
    48   assigned will always be above these cutoff values.</para>
