<sect1 id="ch05-pwdgroup">
<title>Creating passwd and group files</title>
<para>In order for the user and group root to be recognized and to be able to
login, there needs to be an entry in the /etc/passwd and /etc/group file.
Besides the group root a couple of other groups are recommended and needed by
packages. The groups with their GID's below aren't part of any standard.
The LSB only recommends besides a group root a group bin to be present
with GID 1. Other group names and GID's can be chosen by the user. Well
written packages don't depend on GID numbers but just use the group
name, since it doesn't matter all that much what GID a group has. Since there
aren't any standards for groups I won't follow any conventions used by
Debian, RedHat and others. The groups added here are the groups the
MAKEDEV script (the script that creates the device files in the /dev
directory) mentions.</para>
