- It seems that the ISO9660 group *and* the HSF dorks really botched it!
- Why, on a media that most *definitely* is of the WORM category, did they
- implement *fixed* format. I'm no rocket scientist, just a lowly software
- dude, but I could have done a better job. Do the Rock Ridge group have
- any snappy answers to the drawbacks of 9660 and HSF? Can we expect a
- new *variable* format and partitioning scheme in future disk formats?
-
- Once again, the powers that be have coded themselves into a tarpit!!!
