However, iso9660 (RockRidge, actually) has 64 bits of dev_t space; it's actually split into two 32-bit entries specified as "high 32 bits" and "low 32 bits." I'm not positive if Linux expects those to contain major:minor or 0:<16-bit-dev_t>. -hpa -- at work, in private! "Unix gives you enough rope to shoot yourself in the foot."
