			=== AppArmor problems when running Ubuntu 24.04 on Debian 11/12 host ===

			Add this section to <code>/etc/apparmor.d/abstractions/lxc/container-base</code>:

			# 2026/05/01: Ubuntu 24.04 Systemd Sandboxing Compatibility
			# This block allows modern systemd to create nested mount namespaces and use pivot_root.

			# --- 1. Propagation & Transition Rules ---
			mount options=(rw, rslave) -> /,
			mount options=(rw, rshared) -> /,
			mount options=(rw, rprivate) -> /,
			mount options=(rw, slave) -> /run/systemd/incoming/,
			mount options=(rw, rslave) -> /dev/,

			# --- 2. Namespace Creation (Proc/Shm) ---
			mount fstype=proc proc -> /run/systemd/namespace-*/,
			mount fstype=ramfs srcname=ramfs -> /dev/shm/,
			mount fstype=ramfs options=(rw, nosuid, nodev, noexec) -> /dev/shm/,

			# --- 3. The mount-rootfs Sandbox (The Core Fix) ---
			# Allows systemd to populate the sandbox from the real root
			mount options=(rw, rbind) / -> /run/systemd/mount-rootfs/,

			# Allows masking sensitive files/dirs (ProtectHome, ProtectSystem, etc.)
			mount options=(rw, rbind) /run/systemd/inaccessible/ -> /run/systemd/mount-rootfs/,

			# Allows mapping system, proc, run, and tmp into the sandbox
			mount options=(rw, rbind) /{proc,sys,run,tmp,var}/ -> /run/systemd/mount-rootfs/{proc,sys,run,tmp,var}/,
			mount options=(rw, rbind) /run/systemd/unit-root/ -> /run/systemd/mount-rootfs/,

			# Allows the 'remount' phase where systemd sets nosuid/nodev/noexec on sandboxed paths
			mount options=(rw, nosuid, nodev, noexec, remount, bind) -> /run/systemd/mount-rootfs/**,

			# Allows systemd to self-bind inside the sandbox for propagation changes
			mount options=(rw, rbind) /run/systemd/mount-rootfs/ -> /run/systemd/mount-rootfs/,

			# --- 4. Final Handoff ---
			pivot_root /run/systemd/mount-rootfs/ -> /run/systemd/mount-rootfs/**,
			pivot_root /run/systemd/mount-rootfs/ -> /run/**,
