Isn't having a utility such as lttctl mount filesystems against standard
unix semantics? Can you give an example of another standard command that
uses a filesystem and that tries to mount it if it isn't already
mounted? My guess is we should warn about the filesystem not being
mounted, but not try to call mount() directly.
