I've been looking at the SD-UX install disks for HP-UX, and I'm a bit flummoxed. I understand the packaging systems used by SGI, Sun, IBM, xBSD, Linux, etc, but I am completely confused by the HP system. Loading up a disk in the install program and it happily goes through init and install scripts, but mount the disk and look at the filesystem and it has a tree for the software that corresponds with where it goes on the filesystem, but no scripts.
I figure there must be some species of multiple-filesystem-overlay setup with the install scripts in a separate partition/slice/whatever, which seems like an odd way to do it, and the HP SD-UX documentation doesn't elaborate much (just says "to build package use this tool and feed this into it" sort of thing).
Next step I suppose is to look at the raw disk with a hex editor, provided that I'm sufficiently interested, but I thought I'd toss it out here first.
