My guess is that it hits .ssh as well because .ssh is no regular FAT file name, but rather one that can only be created in cmd.exe with "md =2Essh", and probably only works on VFAT, not regular FAT, so a routine looking to match ssh that isn't VFAT-safe will hit .ssh instead. Could it be that we have a bug in x2goclient that purges the ssh directory whenever known_hosts is accessed for writing, or similar?
