Again, on our SysV Pyramids, the whole disk is slice 7. Back when Pyramids ran a kludged 4.2BSD it was slice "h" (still the seventh slice). These, like "c" in FreeBSD, are by convention. You can move things around if you like; the kernel doesn't care. But there are a lot of userland programs, mostly the ones you find documented in the 1M section of the SysV man pages and section 8 of the BSD man pages, that will do surprising things if you don't follow that convention. Solaris, which also claims to be SysV (in some goofy definition of "claims") sticks us with not enough slices. I think we should put this to rest by saying, "It's platform dependent" and leave it at that. -crl -- Chad R.
