I've seen /stand on a few systems (I think SCO OpenServer and / or UnixWare) but never really knew what it was for. I think I had naively assumed it was associated with the kernel and / or booting. Now I'm somewhat more curious what it was. Was it a simplified version of the OS with minimal utilities with fewer dependencies so that the system could boot and load more features. I thought that Linux's initramfs / initrd had the usual suspect files / utilities copied from /. So the idea that a utility in /stand would be different from the same utility in / seems strange to me. > The problem was that it was a little different so you would end up > seeing #ifdef STAND in code for things like fsck, fsdb, even cat. > At Masscomp we ended up with three target environments for a couple of > the system maintenance utilities: the OS, /stand and the boot ROMS. > This was expensive/a PITA to maintain and keep straight, and in the > case of the boot ROM, space was a huge problem. Ya.
