With respect to file options, which have effect only
when a file is opened for output or for combined
input/output, it appears to me that:
In several situations, the R6RS apparently insists
upon raising an exception even though the no-fail
option has been specified.
Opening a file with the no-truncate option by itself

options appears to be equivalent to opening the file
with the no-create option alone.
Opening a file with all three standard options
(no-create, no-fail, and no-truncate) appears to
be equivalent to opening the file with just the
no-create and no-truncate options.
For a case analysis in support of the above
