Question is if there exists a scenario where the requested filesystem type would/could not be found by getvfsbyname() ? I've met this problem myself a number of times - and even in this case I did not spot the spelling error right away ('ext2fs' and not 'ext2'). The returned error 'Operation not supported by device' - atleast to me - indicates that the mount process got much further before running into some kind of problem. The times when I've met this error I've begun inspecting mount options etc before realizing that the fstype had a typo. /Uffe
