systemd-detect-virt: detect s390 virtualization
A system that is running on a logical partition (LPAR) provided by PR/SM has access to physical hardware (except CPU). It is true that PR/SM abstracts the hardware, but only for sharing purposes. Details are statet at: http://publib.boulder.ibm.com/infocenter/eserver/v1r2/topic/eicaz/eicazzlpar.htm -->-- In other words, PR/SM transforms physical resources into virtual resources so that many logical partitions can share the same physical resources. --<-- Still, from the OS point of view, the shared virtual resource is real hardware. ConditionVirtualization must be set to false if the OS runs directly on PR/SM (e.g. in an LPAR). [zj: reorder code so that variables are not allocated when #if-def is false. Add commit message.]
