must be one of: dri, kvm, shm, 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, bluetooth, canbus, per-app-dev-shm. This
option can be used multiple times.
See flatpak-build-finish(1) for the meaning of the various
features.
--disallow=FEATURE
Disallow access to a specific feature. This updates the
[Context] group in the metadata. FEATURE must be one of:
devel, multiarch, bluetooth, canbus, per-app-dev-shm. This
option can be used multiple times.
--filesystem=FILESYSTEM
Allow the application access to a subset of the filesystem.
This overrides to the Context section from the application
metadata. FILESYSTEM can be one of: home, host, host-os,
host-etc, 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. See the "[Context]
filesystems" list in flatpak-metadata(5) for details of the
meanings of these filesystems.
--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, host-os, host-etc, 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.
--add-policy=SUBSYSTEM.KEY=VALUE
Add generic policy option. For example,
"--add-policy=subsystem.key=v1 --add-policy=subsystem.key=v2"
would map to this metadata:
[Policy subsystem]
key=v1;v2;
This option can be used multiple times.
--remove-policy=SUBSYSTEM.KEY=VALUE
Remove generic policy option. 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.
--unset-env=VAR
Unset an environment variable in the application. This
overrides the unset-environment entry in the [Context] group
of the metadata, and the [Environment] group. This option can
be used multiple times.
--env-fd=FD
Read environment variables from the file descriptor FD, and
set them as if via --env. This can be used to avoid
environment variables and their values becoming visible to
other users.
Each environment variable is in the form VAR=VALUE followed
by a zero byte. This is the same format used by env -0 and
/proc/*/environ.
--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.
--no-talk-name=NAME
Don't 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.
--system-no-talk-name=NAME
Don't 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.
--reset
Remove overrides. If an APP is given, remove the overrides
for that application, otherwise remove the global overrides.
--show
Shows overrides. If an APP is given, shows the overrides for
that application, otherwise shows the global overrides.
-v, --verbose
Print debug information during command processing.
--ostree-verbose
