Changelog

• Added support for ID-mapped overlayfs lower layers; eliminates need for shiftfs and Sysbox rootfs chown; requires kernel 5.19+.
• Have Sysbox perform shiftfs and ID-mapping functional checks during init (issue #596).
• Fixed rootfs cloning to prevent inode leakage (for hosts with kernel < 5.19 and no shiftfs) (issue #570).
• Added support for Kubernetes v1.24 to v1.26.
• Added --disable-inner-image-preload flag to sysbox-mgr (speeds up Sysbox container startup).
• Added --syscont-mode flag to sysbox-mgr; allows Sysbox to work in system container mode (default) or regular container mode; the latter is meant for running microservices with stronger isolation.
• Added --disable-shiftfs-on-fuse flag to sysbox-mgr; prevents Sysbox from mounting shiftfs on top of FUSE-backed filesystems (some of which don't work with shiftfs).
• Added few optimizations to expedite I/O operations in procfs/sysfs emulated resources.
• Enhanced life-cycle management of Sysbox daemons in Systemd-free scenarios.
• Prevented concurrent execution of Sysbox daemons (multi-instance problem).
• Improved the handling of ungraceful shutdown scenarios.
• Eliminated Sysbox dependencies on configfs kernel module presence.
• Fixed emulation of /sys/module/nf_conntrack/parameters inside containers.
• Added emulation of /sys/devices/virtual/dmi branch inside containers (for hosts where this or inner resources is not present).
• Hide /sys/kernel/security inside containers (issue #662)
• Don't assign more capabilities to the container than those given to Sysbox itself.
• Don't fail in kernel distros without /lib/modules/.
• Increased the pods-per-node limit from 16 to 4K (Sysbox-CE now matches Sysbox-EE on this regard).
• Extended kubelet config-detection process to multiple drop-in files in sysbox-deploy-k8s daemon-set.
• Incorporated taints during sysbox-deploy-k8s installation process.
• Fixed issue preventing sysbox-deploy-k8s installation in rke2 environments (issue #614).
• Fixed issue preventing proper sysbox-deploy-k8s installation in Azure (issue #612).
