Initial ramdisk which contains a partial or minimal system installation that allows the Linux kernel to load file system drivers as modules which can then access the root partition of the system installation.

XML path
For brevity, I describe the location of data in XML files by their "XML path". For example, the path /foo/bar would refer to a <bar> ... </bar> tag within a <foo> ... </foo> tag which is at the top level of the file. Such paths are the simplest part of the XPath standard.
