46 I haven't seen any install cds that do that, but DSL and, if I recall,
47 TinyCore/MicroCore look for extensions in a default path on the local
48 filesystems. One thing I'm fairly sure on, though, is that without the
49 "-f" flag, mount won't take the risk on an unclean NTFS, and instead
50 just tosses an "are you sure?" message, which would make me presume
51 even those livecds that do look for extensions wouldn't risk the
52 damage there.
