Yes:
if (dpart.part->p_fstype == FS_BSDFFS) {
maxsecsize =
((dpart.disklab->d_secsize > maxsecsize) ?
dpart.disklab->d_secsize : maxsecsize);
size = dpart.part->p_size - CCD_OFFSET;
} else {
#ifdef DEBUG
if (ccddebug & (CCDB_FOLLOW|CCDB_INIT))
printf("ccd%d: %s: incorrect partition type\n",
ccd->ccd_unit, ci->ci_path);
#endif
while (ci >= cs->sc_cinfo) {
free(ci->ci_path, M_DEVBUF);
ci--;
}
free(cs->sc_cinfo, M_DEVBUF);
return (EFTYPE);

And it doesn't mean it's correct to do so. Just yesterday I saw a
case where somebody had wiped out his system disk while trying to
configure a ccd. Vinum won't let you do that.
