That’s rpm, suse Linux 1.0 was never built off the same source or installer that Redhat Linux was.
Do you have a historical example where any suse distribution used redhat based source? As opensuse as I said only used the rpm package manager, it never used any other components of a redhat derived install.
Source: I work there and can find zero redhat strings in any old source code from that era, the old greybeards took offense to the implication that suse was ever based on redhat other than using rpm which at the time was about it for packaging.
All they did was start to use rpm instead of tar for packaging.
My late gram too, every dam time: I don’t know young man, can you do a thing or may you? Why are you asking my permission about your ability to do stuff?
She was a stickler for using may.
