ostree-checkout - Check out a commit into a filesystem

       Checks out the given commit into the filesystem under directory DESTINATION. If DESTINATION is not
       specified, the COMMIT will become the destination checkout target. If COMMIT destination already exists,
       command will error unless --union option is selected.

       ostree-checkout - Check out a commit into a filesystem

--user-mode, -U
           Do not change file ownership or initialize extended attributes.

       --subpath="PATH"
           Checkout sub-directory PATH.

       --union
           Keep existing directories and unchanged files, overwrite existing files.

       --union-add
           Keep existing directories and files.

       --union-identical
           Like --union, but error out if a file would be replaced with a different file. Add new files and
           directories, ignore identical files, and keep existing directories. Requires -H.

       --whiteouts
           Process whiteout files (Docker style).

       --process-passthrough-whiteouts
           Enable overlayfs whiteout extraction into 0:0 character devices. Overlayfs whiteouts are encoded
           inside ostree as .ostree-wh.filename and extracted as 0:0 character devices. This is useful to carry
           container storage embedded into ostree.

       --allow-noent
           Do nothing if specified path does not exist.

       --from-stdin
           Process many checkouts from standard input.

       --from-file="FILE"
           Process many checkouts from input file.

       --fsync="POLICY"
           POLICY is a boolean which specifies whether fsync should be used or not. Default to true.

       --require-hardlinks, -H
           Do not fall back to full copies if hardlinking fails.

       --force-copy-zerosized, -z
           This option does nothing; the functionality is now always on by default.

       --force-copy, -C
           Never hardlink (but may reflink if available).

       --bareuseronly-dirs, -M
           Suppress mode bits outside of 0775 for directories (suid, world writable, etc.).

       --skip-list="FILE"
           Skip checking out the absolute file paths listed in FILE, one per line.

       --selinux-policy
           Set SELinux labels based on policy in root filesystem PATH (may be /). This implies --force-copy.

       --composefs
           Only generate a composefs, not a directory.

       --composefs-noverity
           Only generate a composefs, not a directory; fsverity digests will not be included. This is best used
           for "opportunistic" use of composefs.
