Uyuni/SUSE Manager build client tools for each of the supported operating systems: SLES 11, SLES 12, SLES 15, RHEL 6, RHEL 7, RHEL 8, Ubuntu 16.04, Ubuntu 18.04, Ubuntu 20.04, Debian 9, Debian 10... the list is long. This is required because each operating system has different base libraries (glibc, OpenSSL, Python version, etc).

A few months ago, the SUSE Manager development team started a (yet unfinished) research task to try to build Salt and all the required dependencies (minus glibc and OpenSSL, because it would break FIPS certification) so that we can always ship the latest version of Salt on each client operating system:

https://build.opensuse.org/project/show/systemsmanagement:saltstack:bundle

Can we go further? Can we build a single Python+Salt bundle for all the supported operating systems (even OpenSSL, at the cost of not managing FIPS-enabled clients?

In fact, can we go infinite and build a single αcτµαlly pδrταblε εxεcµταblε bundle so that we have a single bundle that will work on every operating system: all versions of SLES, all versions of RHEL, FreeBSD, NetBSD, macOS, Windows... everything with the same binary bundle!

Cosmopolitan is a very cool open source project started by Justine Tunney which makes possible to build universal executables ("actually portable executables") that run everywhere.

NB: after building the Python+Salt APE bundle, some additional work will be required in Uyuni, but that's to be resolved later :-)
