deluser.conf(5)


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 option takes the form option = value.
   Double  or  single  quotes are allowed around the value.  Comment lines
   must have a hash sign (#) at the beginning of the line.

   deluser(8)   and   delgroup(8)   also   read   /etc/adduser.conf,   see
   adduser.conf(8);  settings  in deluser.conf may overwrite settings made
   in adduser.conf.

   The valid configuration options are:

   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).

   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.

   BACKUP If  REMOVE_HOME  or  REMOVE_ALL_FILES is activated all files are
          backuped 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.

   BACKUP_TO
          If  BACKUP  is  activated, BACKUP_TO specifies the directory the
          backup is written to. Default is the current directory.

   NO_DEL_PATHS
          A list of regular expressions, space separated. All files to  be
          deleted in course of deleting home directories or deleting files
          owned by the user to be deleted  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.

          In  other  words: By default 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  user  who  belong  to  this
          group. Defaults to 0.

   EXCLUDE_FSTYPES
          A  regular  expression  which  describes  all file systems which
          should be excluded when looking  for  files  of  a  user  to  be
          deleted. Defaults to "(proc|sysfs|usbfs|devpts|tmpfs|afs)".
