Changing fs root dir fibration plugin would do that if the root dir was empty.
Current code does not allow it.  

So, the problen cannot be fully solved.  However, you can re-create all second

fs/reiser4/vfs_opts.c:reiser4_parse_options contains opts[] -- an array of 
all reiser4 mount option descriptions.

...
	opt_desc_t opts[] = {
		/* trace_flags=N

                   set trace flags to be N for this mount. N can be C numeric

		SB_FIELD_OPT(trace_flags, "%i"),
		/* log_flags=N
