- Point is that minixfs update knows which drives to do. If you don't and
- call Dcntl() on any drive existing, you'll end up starting the floppy each
- time probably. That`s where I ended up when making an external `sync'
- program for minixfs, and will probably disturb you, as it disturbed me,
- I can tell you...
-
- So you might consider an option to map out some drives which are likely
- not to be minix ones. Or something like this.
-
- Better: Make minixfs use the cache mode in a `per drive' way and assume
- that floppies won't use the TURBO mode. You might think of other reasons
- why this might be a good idea... Stephen??????? :-)
