Yes, of course – my mistake for not being clear enough with respect to the “Open Build Service (OBS)” versus the «public instance of» “openSUSE Build Service” jungle …

I just discovered an interesting on one of those »Stackexchange«/»Superuser« forums:
https://superuser.com/questions/639351/does-recompiling-a-program-produce-a-bit-for-bit-identical-binary (»Does recompiling a program produce a bit-for-bit identical binary?«)
Much interesting info with links to more info, especially gcc-specific features like …
-frandom-seed=string
This option provides a seed that GCC uses when it would otherwise
use random numbers. It is used to generate certain symbol names
that have to be different in every compiled file. It is also used
to place unique stamps in coverage data files and the object files
that produce them. You can use the -frandom-seed option to produce
reproducibly identical object files.
The string should be different for every file you compile.
It’s another proverbial can of worms that just managed to remind me once more why I’ve chosen all that »blinkenlights« stuff as a hobby fourty years ago (and later as a profession).
Cheers!
