Sometimes, non-ramfs initrd root are useful. Eg, for kdump, because initramfs is memory consuming, so mount a compressed image in earlier initrd, chroot into it then let systemd do the rest of job is a good solution. But systemd doesn't recognize the initrd environment if rootfs is not a temporary fs. This is a reasonable check, because switch-root in initrd will wipe the whole rootfs, will be a disaster if there are any misdetect. So extend SYSTEMD_IN_INITRD environment variable, now it accepts boolean value and two extra keyword, "auto" and "lenient". "auto" is same as before, and it's the default value. "lenient" will let systemd bypass the rootfs check.
