129		All bits in Xen's start-flags are represented as
130		boolean files, returning '1' if set, '0' otherwise.
131		This takes the place of the defunct /proc/xen/capabilities,
132		which would contain "control_d" on dom0, and be empty
133		otherwise.  This flag is now exposed as "initdomain" in
134		addition to the "privileged" flag; all other possible flags
135		are accessible as "unknownXX".
