These are modified versions of the official Ramdisk designed to grant shell access (SSH) or allow file system mounting without passcode entry. Historically, tools like redsn0w or idevicerestore used custom Ramdisks. For the iPhone XR, modern tools like (for checkm8 devices) do not work because the XR is not vulnerable to checkm8.
