Module image 

APIs for operating on container images in the bootc storage.

bootc image set-unified

set_unified_entrypoint dispatches to set_unified (ostree backend) or set_unified_composefs (composefs backend). Both pull the currently booted image into bootc-owned containers-storage so that future upgrade/switch operations can use the unified storage path.

In the planned three-store architecture (see crate::store), this will require a reflink-capable filesystem (XFS or btrfs) by default to enable block sharing. The planned --allow-copy flag will opt into a byte copy for environments like ext4 where podman access to the OS image matters more than disk efficiency.

Structs

ImageOutput 🔒

Enums

ImageListTypeColumn 🔒

Constants

IMAGE_DEFAULT 🔒

The name of the image we push to containers-storage if nothing is specified.

Functions

get_imgrefs_for_copy 🔒

Returns the source and target ImageReference If the source isn’t specified, we use booted image If the target isn’t specified, we push to containers-storage with our default image

image_exists_in_host_storage 🔒

Check if an image exists in the default containers-storage (podman storage).

imgcmd_entrypoint 🔒

Thin wrapper for invoking podman image <X> but set up for our internal image store (as distinct from /var/lib/containers default).

list_entrypoint 🔒

list_host_images 🔒

list_host_images_composefs 🔒

list_images 🔒

list_logical_images 🔒

push_entrypoint 🔒

Implementation of bootc image push-to-storage.

set_unified 🔒

Inner implementation of set_unified for ostree that accepts a storage reference.

set_unified_composefs 🔒

Composefs implementation of set_unified: pull the booted image into bootc-owned containers-storage so future upgrades use the unified (zero-copy) path automatically.

set_unified_entrypoint 🔒

Re-pull the currently booted image into the bootc-owned container storage.
