Iconoclastic? The IBM partitioning scheme basically says "This is a partition. It starts HERE. It ends HERE. It has this TYPE." How iconoclastic is that?
Iconoclastic would be interleaved or striped partitions, things like "This partition begins HERE and continues on, every sixth cylinder, until HERE," or something like that. That kind of thing is actually a good idea, assuming most files on the partition can fit into one cylinder, because then catastrophic head crashes don't have as much chance of wiping out huge chunks of any one partition or filesystem. But it's still more iconoclastic than the old PC scheme.
Besides, multiple partitions make all kinds of things simpler and safer. I'm paranoid about using "find" to do just about anything, but as long as I have -xdev in its command line somewhere I feel much safer because I know that, at the worst, a typo can only blow away a SINGLE filesystem. So by keeping /usr on a seperate partition, and /home on yet another, I reduce the risk of pissing off 15 users by being stupid, and I run less risk of having to download all my patches and software again (since /usr/local is a symlink to /home/local). Hell, it even makes complete system reinstalls much simpler. Assuming I don't do something dumb and mis-specify a partition during the install, I don't even have to back anything up except the vital configs, which I tar up before I begin anyway.
Cheers, Max
