/etc/adduser.conf - configuration file for adduser(8) and addgroup(8).
The file /etc/adduser.conf contains defaults for the programs
adduser(8) and addgroup(8). Each option takes the form option = value.
Double or single quotes are allowed around the value. Comment lines
must have a pound sign (#) in the first line.
The valid configuration options are:
DSHELL The login shell to be used for all new users. Defaults to
DHOME The directory in which new home directories should be created.
Defaults to /home.
GROUPHOMES [Toc] [Back]
If this is set to yes, the the home directories will be created
as /home/[groupname]/user. Defaults to no.
LETTERHOMES [Toc] [Back]
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 dynamically allocated system user
UIDs. Default to 100 - 999.
FIRST_UID and LAST_UID
specify an inclusive range of dynamically allocated normal user
UIDs. Default to 1000 - 29999.
USERGROUPS [Toc] [Back]
If this is set to yes, then each created user will be given
their own group to use and their home directories will be g+s.
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 [Toc] [Back]
If USERGROUPS is no, then USERS_GID is the GID given to all
newly-created users. The default value is 100.
QUOTAUSER [Toc] [Back]
If set to a nonempty value, new users will have quotas copied
from that user. The default is empty.
DIR_MODE [Toc] [Back]
If set to a valid value (e.g. 0755 or 755), directories created
will have the specified permissions. Otherwise 0755 is used as
SETGID_HOME [Toc] [Back]
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.
