Ubuntu Manpage: dpkg-statoverride - override ownership and mode of files

NAME

       dpkg-statoverride - override ownership and mode of files

SYNOPSIS

       dpkg-statoverride [option...] command

DESCRIPTION

       “stat overrides” are a way to tell dpkg(1) to use a different owner or mode for a path when a package is
       installed (this applies to any filesystem object that dpkg handles, including directories, devices,
       etc.).  This can be used to force programs that are normally setuid to be install without a setuid flag,
       or only executable by a certain group.

       dpkg-statoverride is a utility to manage the list of stat overrides.  It has three basic functions:
       adding, removing and listing overrides.

COMMANDS

       --add user group mode path
           Add  an  override  for  path.   path does not need to exist nor be known to dpkg when this command is
           used; the override will be stored and used later.  Users and groups can be specified  by  their  name
           (for  example root or nobody), or by their number by prepending the number with a ‘#’ (for example #0
           or #65534).  The mode needs to be specified in octal.

           If --update is specified and path exists, it is immediately set to the new owner and mode.

       --remove path
           Remove an override for path, the status of path is left unchanged by this command.

       --list [glob-pattern]
           List all overrides.  If a glob pattern is specified restrict the output to overrides which match  the
           glob.

       --help
           Show the usage message and exit.

       --force-help
           Give help about the --force-thing options (since dpkg 1.19.5).

       --version
           Show the version and exit.

OPTIONS

--admindir directory
Set the administrative directory to directory. This is where the statoverride file is stored.
Defaults to «/var/lib/dpkg» if DPKG_ADMINDIR has not been set.

--instdir directory
Set the installation directory, which refers to the directory where packages get installed (since
dpkg 1.19.2). Defaults to «/» if DPKG_ROOT has not been set.

--root directory
Set the root directory to directory, which sets the installation directory to «directory» and the
administrative directory to «directory/var/lib/dpkg» (since dpkg 1.19.2) if DPKG_ROOT has not been
set.

--force-things
--no-force-things, --refuse-things
Force or refuse (no-force and refuse mean the same thing) to do some things (since dpkg 1.19.5).
things is a comma separated list of things specified below. --force-help displays a message
describing them. Things marked with (*) are forced by default.

Warning: These options are mostly intended to be used by experts only. Using them without fully
understanding their effects may break your whole system.

all:
Turns on (or off) all force options.

statoverride-add:
Overwrite an existing stat override when adding it (since dpkg 1.19.5).

statoverride-remove:
Ignore a missing stat override when removing it (since dpkg 1.19.5).

security-mac(*):
Use platform-specific Mandatory Access Controls (MAC) based security when installing files into
the filesystem (since dpkg 1.19.5). On Linux systems the implementation uses SELinux.

not-root:
Try to (de)install things even when not root (since dpkg 1.21.8).

--force
Force an action, even if a sanity check would otherwise prohibit it. This is necessary to override
an existing override. This option is deprecated (since dpkg 1.19.5), it is replaced by --force-all.

--update
Immediately try to change the path to the new owner and mode if it exists.

--quiet
Be less verbose about what we do.

EXIT STATUS

       0   The requested action was successfully performed.

       1   For --list, if there are no overrides or none match the supplied glob.

       2   Fatal or unrecoverable error due to invalid command-line usage, or interactions with the system, such
           as accesses to the database, memory allocations, etc.

ENVIRONMENT

       DPKG_ROOT
           If set and the --instdir or --root options have not been specified, it will be used as the filesystem
           root directory (since dpkg 1.19.2).

       DPKG_ADMINDIR
           If set and the --admindir or --root options have not been specified, it will be used as the dpkg data
           directory.

       DPKG_DEBUG
           Sets the debug mask (since dpkg 1.21.10) from an octal  value.   The  currently  accepted  flags  are
           described in the dpkg --debug option, but not all these flags might have an effect on this program.

       DPKG_FORCE
           If  set and none of the --force-... options have been specified, it will be used as the force options
           to use (since dpkg 1.19.5).

       DPKG_COLORS
           Sets the color mode (since dpkg 1.18.5).  The currently accepted values are: auto  (default),  always
           and never.

FILES

       /var/lib/dpkg/statoverride
           File  which  contains  the  current  list of stat overrides of the system.  It is located in the dpkg
           administration directory, along with other files important to dpkg, such as status or available.

           Note: dpkg-statoverride preserves the old copy of this file, with extension “-old”, before  replacing
           it with the new one.
