1. Users can decided whether to use ntfs-3g themselves, if so, just
slect it at "make menuconfig->utility->filesystem->ntfs-3g-utils";
2. This sentence "access("/sbin/mount.ntfs-3g", X_OK)" does the test
for its presence or not;
3. There are 2 way to mount devices of ntfs filesystem, default is
readonly while writable with fuseblk(ntfs-3g),
so we need to do a special test here that avoid user remount it
again and again when system boot.

Subject:Re: [OpenWrt-Devel] [PATCH, V2] fstools: mount ntfs with ntfs-3g
utility if it exist
I’m not seeing where “mount.ntfs-3g” is being set as the program to use... and
should the test for the presence and modes of the program be generic? i.e.
regardless of what type of FS or which program you use to mount it, you’ll want
to test for its presence.
So these are really two independent things.
