Well, some string searching in their binaries reveals:
$ strings -a ntoskrnl.exe | grep Ros
CcRosInternalFreeCacheSegment failed, status = %x
CcRosUnmapCacheSegment failed, status = %x
CCRosUnmapCacheSegment failed, status = %x
CcRosInitializeFileCache
CcRosReleaseFileCache
KeRosDumpStackFrames
KeRosPrintAddress
$ strings -a ver.dll | grep ReactOS
OS2 Images not supported under ReactOS at this time.
I think we should inform them they are in violation of the GPL and thereby
breaking copyright law. Jason, maybe you can send them an email?
