The very first Unix I ever encountered, AT&T 6th Edition on a PDP-11/34 with RK05 disks, used what FreeBSD has (until recently) called "dangerously dedicated" disks. Ditto the first BSD- derived Unix I used, SunOS 3.5 on a Sun-3/160 with the Xylogics SMD disk controller. Of course there was nothing dangerous about it then, because no one had ever heard of installing more than one OS on any given disk pack or cartridge. (Even the large multi-platter disk packs were small enough that one ordinarily needed multiple packs per OS; there was no way anyone would have wanted to squeeze multiple OS onto a pack.) Prior to the IBM PC-AT -- the first PC to have a hard drive -- how many systems _did_ support multiple installs?
