Checkmk versions & editions

1.6.0b1	Checkmk Raw (CRE), Checkmk Enterprise (CEE), Checkmk MSP (CME)
1.5.0b7	Checkmk Raw (CRE), Checkmk Enterprise (CEE), Checkmk MSP (CME)

Up to and including 1.4.0*, df would report UNKNOWN when confronted with a vanished filesystem. A regression in 1.5.0 versions previous to this lead to the check crashing instead. This has been fixed.
