NAME¶
flatpak-override - Override application requirementsSYNOPSIS¶
flatpak override [OPTION...] APP
DESCRIPTION¶
Overrides the application specified runtime requirements. This can be used to grant a sandboxed application more or less resources than it requested. By default the application gets access to the resources it requested when it is started. But the user can override it on a particular instance by specifying extra arguments to flatpak run, or every time by using flatpak override. Unless overridden with the --user or --installation options, this command changes the default system-wide installation.OPTIONS¶
The following options are understood: -h, --helpShow help options and exit.
--user
Update a per-user installation.
--system
Update the default system-wide installation.
--installation=NAME
Updates a system-wide installation specified by NAME
among those defined in /etc/flatpak/installations.d. Using
--installation=default is equivalent to using --system.
--share=SUBSYSTEM
Share a subsystem with the host session. This overrides
the Context section from the application metadata. SUBSYSTEM must be one of:
network, ipc. This option can be used multiple times.
--unshare=SUBSYSTEM
Don't share a subsystem with the host session. This
overrides the Context section from the application metadata. SUBSYSTEM must be
one of: network, ipc. This option can be used multiple times.
--socket=SOCKET
Expose a well-known socket to the application. This
overrides to the Context section from the application metadata. SOCKET must be
one of: x11, wayland, pulseaudio, system-bus, session-bus. This option can be
used multiple times.
--nosocket=SOCKET
Don't expose a well-known socket to the application. This
overrides to the Context section from the application metadata. SOCKET must be
one of: x11, wayland, pulseaudio, system-bus, session-bus. This option can be
used multiple times.
--device=DEVICE
Expose a device to the application. This overrides to the
Context section from the application metadata. DEVICE must be one of: dri,
kvm, all. This option can be used multiple times.
--nodevice=DEVICE
Don't expose a device to the application. This overrides
to the Context section from the application metadata. DEVICE must be one of:
dri, kvm, all. This option can be used multiple times.
--allow=FEATURE
Allow access to a specific feature. This updates the
[Context] group in the metadata. FEATURE must be one of: devel, multiarch.
This option can be used multiple times.
The devel feature allows the application to access certain syscalls such as
ptrace(), and perf_event_open().
The multiarch feature allows the application to execute programs compiled for an
ABI other than the one supported natively by the system. For example, for the
x86_64 architecture, 32-bit x86 binaries will be allowed as well.
--disallow=FEATURE
Disallow access to a specific feature. This updates the
[Context] group in the metadata. FEATURE must be one of: devel, multiarch.
This option can be used multiple times.
--filesystem=FS
Allow the application access to a subset of the
filesystem. This overrides to the Context section from the application
metadata. FS can be one of: home, host, xdg-desktop, xdg-documents,
xdg-download xdg-music, xdg-pictures, xdg-public-share, xdg-templates,
xdg-videos, xdg-run, xdg-config, xdg-cache, xdg-data, an absolute path, or a
homedir-relative path like ~/dir or paths relative to the xdg dirs, like
xdg-download/subdir. The optional :ro suffix indicates that the location will
be read-only. The optional :create suffix indicates that the location will be
read-write and created if it doesn't exist. This option can be used multiple
times.
--nofilesystem=FILESYSTEM
Remove access to the specified subset of the filesystem
from the application. This overrides to the Context section from the
application metadata. FILESYSTEM can be one of: home, host, xdg-desktop,
xdg-documents, xdg-download xdg-music, xdg-pictures, xdg-public-share,
xdg-templates, xdg-videos, an absolute path, or a homedir-relative path like
~/dir. This option can be used multiple times.
--env=VAR=VALUE
Set an environment variable in the application. This
overrides to the Context section from the application metadata. This option
can be used multiple times.
--own-name=NAME
Allow the application to own the well-known name NAME on
the session bus. This overrides to the Context section from the application
metadata. This option can be used multiple times.
--talk-name=NAME
Allow the application to talk to the well-known name NAME
on the session bus. This overrides to the Context section from the application
metadata. This option can be used multiple times.
--system-own-name=NAME
Allow the application to own the well known name NAME on
the system bus. If NAME ends with .*, it allows the application to own all
matching names. This overrides to the Context section from the application
metadata. This option can be used multiple times.
--system-talk-name=NAME
Allow the application to talk to the well known name NAME
on the system bus. If NAME ends with .*, it allows the application to talk to
all matching names. This overrides to the Context section from the application
metadata. This option can be used multiple times.
--persist=FILENAME
If the application doesn't have access to the real
homedir, make the (homedir-relative) path FILENAME a bind mount to the
corresponding path in the per-application directory, allowing that location to
be used for persistent data. This overrides to the Context section from the
application metadata. This option can be used multiple times.
-v, --verbose
Print debug information during command processing.
--version
Print version information and exit.
