They seem to be ignored now.
This is the 1.1 code:
/*
* Flag indicating
* Nothing to do....
*/
static int isofs_rrip_idflag( p, ana )
ISO_RRIP_IDFLAG *p;
ISO_RRIP_ANALYZE *ana;
{
char buf[3];
buf[0] = p->h.type[0];
buf[1] = p->h.type[1];
buf[2] = 0x00;
printf("isofs:%s[%d] idflag=0x%x\n",
buf,
isonum_711(p->h.length),
p->flags );
return 0;
}
...and this is from 2.2-current:
/*
* Flag indicating
*/
static int
cd9660_rrip_idflag(p,ana)
ISO_RRIP_IDFLAG *p;
ISO_RRIP_ANALYZE *ana;
{
ana->fields &= isonum_711(p->flags)|~0xff; /* don't touch high bits */
/* special handling of RE field */
if (ana->fields&ISO_SUSP_RELDIR)
return cd9660_rrip_reldir(p,ana);
return ISO_SUSP_IDFLAG;
}
(Relocated directories seem to be handled in another piece of code in
1.1, or there's simply a bug.)
Note that there are a few more ``Nothing to do...'' functions in the
1.1 code that might issue blatant printf's.
I don't have the time to look into the CD9600 standard right now in
order to see what the RR's might be for.

Never trust an operating system you don't have sources for. ;-)
