Introduce the `systemd.break=` kernel command line option to allow stopping the boot process at a certain point and spawn a debug shell. After exiting this shell, the system will resume booting. It accepts the following values: - `pre-udev`: before starting to process kernel uevents (initrd and host). - `pre-basic`: before leaving early boot and regular services start (initrd and host). - `pre-mount`: before the root filesystem is mounted (initrd). - `pre-switch-root`: before switching root (initrd).
