The API opens [in this instance] /dev/stderr with O_TRUNC: https://github.com/libguestfs/libguestfs/blob/master/src/proto.c#L752 So if you redirect stderr to a file, then the file gets truncated. A quick fix is to use `tee' (or another program) in the redirection, since a pipe ignores truncations. The real fix is to modify the guestfs_download API to allow the truncation behaviour to be optional.
