Did you notice that selection (checked gadget) of ...

 1 = Turn on automatic symlink resolution
 2 = Turn on case independence.  If you are familiar with the
     Amiga filesystem, you probably want to turn this on.
 4 = Make filesystem respect UNIX paths and not AmigaDOS paths

... in BBFSTool on, results in a PreAlloc value of 0. This is in
contradiction with the doc/user_manual.

I tested it and a PreAlloc Value of 0 (with mounting as DOSDriver or
through the RDB) really means that the access to files is case
dependant [2]. This would mean that the doc/user_manual is correct,
and BFFSTool shows wrong figures. I confirmed this by setting PreAloc
of the BSDROOT: to 0 and the BSDUSR: to 7. BFFSTool showed the
opposite!

The first option (automatic symlink resolution) behaves opposite of
what is expected. "0" switches it *ON*, "1" *OFF*!

Looking at the third option (respect UNIX paths), does this incluence
something else than the 'cd /' command (goes to / [UNIX] or one
directory up [AmigaOS])?

Why is this not done immediately?
It is logical that '-rw-r--r--' should be used instead of
'-rw--wx-wx'. Anyway, it's not explained how the group/other
permissions are mapped to the UNIX side when copying from AmigaOS to
UNIX. Are the group/other permissions always 'r--' when this flag is
set and '-wx' when it's unset?

64 = Report space free relative to minfree (instead of actual)

C:Info showed indeed some differences (52% full or 57% full). But what
is the difference between both settings?
