NAME
/etc/deluser.conf - configuration file for deluser(8) and delgroup(8).
DESCRIPTION
The file /etc/deluser.conf contains defaults for the programs deluser(8) and 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
column.
deluser(8) and delgroup(8) also read /etc/adduser.conf, see adduser.conf(5); settings in deluser.conf may
overwrite settings made in adduser.conf.
The valid configuration options are:
BACKUP If REMOVE_HOME or REMOVE_ALL_FILES is activated, all files are backed up before they are removed.
The backup file that is created defaults to username.tar(.gz|.bz2) in the directory specified by
the BACKUP_TO option. The compression method is chosen to the best that is available. Values may
be 0 or 1. Defaults to 0.
BACKUP_SUFFIX
Select compression algorithm for a home directory backup. Can be set to any suffix recognized by
tar --auto-compress. Defaults to .gz.
BACKUP_TO
If BACKUP is activated, BACKUP_TO specifies the directory the backup is written to. Defaults to
the current directory.
EXCLUDE_FSTYPES
A regular expression which describes all filesystem types which should be excluded when looking
for files of a user to be deleted. Defaults to "(proc|sysfs|usbfs|devtmpfs|devpts|afs)".
NO_DEL_PATHS
A list of regular expressions, space separated. All files to be deleted in course of deleting the
home directory or user-owned files elsewhere are checked against each of these regular
expressions. If a match is detected, the file is not deleted. Defaults to a list of system
directories, leaving only /home. Therefore only files below /home belonging to that specific user
are going to be deleted.
ONLY_IF_EMPTY
Only delete a group if there are no users belonging to this group. Defaults to 0.
REMOVE_ALL_FILES
Removes all files on the system owned by the user to be removed. If this option is activated
REMOVE_HOME has no effect. Values may be 0 or 1. Defaults to 0.
REMOVE_HOME
Removes the home directory and mail spool of the user to be removed. Value may be 0 (don't
delete) or 1 (do delete). Defaults to 0.
