* I once saw a copy of a RRIP spec which mentioned RR. Here i just use
* the same constant 5 bytes as produced by mkisofs.
* The meaning of the payload byte is documented e.g. in
* /usr/src/linux/fs/isofs/rock.h
* It announces the presence of entries PX, PN, SL, NM, CL, PL, RE, TF
* by payload byte bits 0 to 7.
