Module status 

Structs

BootloaderEntry 🔒

ComposefsCmdline 🔒

A parsed composefs command line

DeploymentBootInfo 🔒

Information about a deployment for soft reboot comparison

ImgConfigManifest 🔒

Used for storing the container image info alongside of .origin file

StagedDeployment 🔒

The JSON schema for staged deployment information stored in /run/composefs/staged-deployment

Constants

BLS_ENTRIES_DIR 🔒

Directory where BLS-compatible bootloaders expect Type 1 boot entries.

GRUB_DIRS 🔒

Directories where GRUB keeps its own configuration and modules. Their presence means GRUB owns the boot flow even if BLS Type 1 entries also exist, because GRUB can consume those entries itself via the blscfg module — Fedora and RHEL enable exactly that with GRUB_ENABLE_BLSCFG=true. /boot/grub2 is the Fedora/RHEL path, /boot/grub the Debian/Ubuntu one.

Functions

build_composefs_karg 🔒

Render a composefs karg that identifies the EROFS format of digest.

classify_bootloader 🔒

Pure classifier for the bootloader kind, split from I/O for testability.

composefs_booted 🔒

Detect if we have composefs=<digest> in /proc/cmdline

composefs_deployment_status_from 🔒

find_bls_entry 🔒

get_bootloader 🔒

get_composefs_status 🔒

Get composefs status using provided storage and booted composefs data instead of scraping global state.

get_container_manifest_and_config 🔒

imgref = transport:image_name

get_imginfo 🔒

Retrieves the OCI manifest and config for a deployment from the composefs repository.

get_sorted_grub_uki_boot_entries_staged 🔒

Get the staged grub UKI menuentries

get_sorted_staged_type1_boot_entries 🔒

image_version_and_created 🔒

Version and created timestamp for a composefs deployment image.

list_type1_entries 🔒

read_staged_deployment 🔒

reconcile_composefs_cmdline_with_mount_source 🔒

rollback_queued_from_first_entry 🔒
