dpkg-statoverride - override ownership and mode of files
` stat overrides
' are a way to tell dpkg(1)
to use a different
owner or mode for a file when a package is installed. (note: I use the word
`file' here, but in reality this can be 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.
is a utility to manage the list of stat overrides. It
has three basic functions: adding, removing and listing overrides.
- --add user group mode file
- Add an override for file. file does not need
to exist 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 file exists, it is immediately set to
the new owner and mode.
- --remove file
- Remove an override for file, the status of
file 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. If there are no overrides or
none match the glob dpkg-statoverride will exit with an exitcode of
- Show the usage message and exit.
- Show the version and exit.
- --admindir directory
- Change the directory of the dpkg database where the
statoverride file is also stored. Defaults to /var/lib/dpkg.
- Force an action, even if a sanity check would otherwise
prohibit it. This is necessary to override an existing override.
- Immediately try to change the file to the new owner and
mode if it exists.
- Be less verbose about what we do.
- If set and the --admindir option has not been
specified, it will be used as the dpkg data directory.
- 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.
