# It locates the pinned CISS GPG key material on the live medium, optionally verifies this script's signed hash,
# optionally verifies signed checksum files, and checks the first matching checksum manifest with the matching digest tool. It

# Module summary:
# - Run early cryptroot handling before live filesystem discovery.
# - Parse live-boot parameters, apply debug/read-only/network setup, and load initramfs configuration.
# - Locate or reuse the live filesystem from network, iSCSI, plain root, memdisk, LVM-backed media, or the
# CISS encrypted SquashFS preseed.
# - Verify checksums, optionally copy live media to RAM or disk, and mount the final live root via unionfs or image stacking.
# - Transfer selected runtime configuration into the target root, validate the mounted root, configure fstab/netbase/swap, and
# preserve boot logs.
