Ubuntu Feisty 7.04 manual page repository
Ubuntu is a free computer operating system based on the Linux kernel. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.
The file /etc/adduser.conf contains defaults for the programs delgroup(8). Each line holds a single value pair in the form option = value. Double or single quotes are allowed around the value, as is whitespace around the equals sign. Comment lines must have a hash sign (#) in the first line. The valid configuration options are: DSHELL The login shell to be used for all new users. Defaults to /bin/bash. DHOME The directory in which new home directories should be created. Defaults to /home. GROUPHOMES If this is set to yes, the home directories will be created as /home/[groupname]/user. Defaults to no. LETTERHOMES If this is set to yes, then the home directories created will have an extra directory inserted which is the first letter of the loginname. For example: /home/u/user. Defaults to no. SKEL The directory from which skeletal user configuration files should be copied. Defaults to /etc/skel. FIRST_SYSTEM_UID and LAST_SYSTEM_UID specify an inclusive range of UIDs from which system UIDs can be dynamically allocated. Default to 100 - 999. FIRST_UID and LAST_UID specify an inclusive range of UIDs from which normal user’s UIDs can be dynamically allocated. Default to 1000 - 29999. USERGROUPS If this is set to yes, then each created user will be given their own group to use. If this is no, then each created user will be placed in the group whose GID is USERS_GID (see below). The default is yes. USERS_GID If USERGROUPS is no, then USERS_GID is the GID given to all newly-created users. The default value is 100. DIR_MODE If set to a valid value (e.g. 0755 or 755), directories created will have the specified permissions. Otherwise 0755 is used as default. SETGID_HOME If this is set to yes, then home directories for users with their own group ( USERGROUPS=yes ) will have the setgid bit set. This was the default setting for adduser versions << 3.13. Unfortunately it has some bad side effects, so we no longer do this per default. If you want it nevertheless you can still activate it here. QUOTAUSER If set to a nonempty value, new users will have quotas copied from that user. The default is empty. NAME_REGEX User names are checked against this regular expression. If the name doesn’t match this regexp, user creation is refused unless --force-badname is set. With --force-badname set, only weak checks are performed. The default is the most conservative ^[a- z][-a-z0-9]*$. SKEL_IGNORE_REGEX Files in /etc/skel/ are checked against this regex, and not copied to the newly created home directory if they match. This is by default set to the regular expression matching files left over from unmerged config files (dpkg-(old|new|dist)). ADD_EXTRA_GROUPS Setting this to something other than 0 (the default) will cause adduser to add newly created non-system users to the list of groups defined by EXTRA_GROUPS (below). EXTRA_GROUPS This is the list of groups that new non-system users will be added to. By default, this list is ’dialout cdrom floppy audio src video lp users’
