Linux is just a kernel, so every distribution is a somewhat similar yet completely different operating system.

Reality is, most software targets CentOS / RHEL, OpenSUSE / SLES and Debian / Ubuntu. That's exactly two packaging formats, RPM and DPKG.

Now, let's presume for the purpose of illustration that learning both of those takes 100 hours (it takes much less): to learn Chef, Puppet, Docker, Ansible and Kubernetes to any degree of proficiency takes about 1,000 hours. Where's the business value?

Try to install a random RPM package targeted to Red-Hat on SLES to see how far you will go.

That's again due to incompetence and not a fault of RPM. My own spec files build cleanly across both without any additional effort. It's not rocket science but insight.

Ah, like the C based security exploits are the fault of programmer and not the lack of safety features to start with.

[Annatar]

Absolutely correct. Those who do not understand the hardware on the register and machine code level should go master that first before dabbling with C.

One has to learn to walk before one attempts to run. Working on and with computers requires competence and insight; no technology can replace that nor ameliorate it.

[pjmlp]

Nice point of view, then you wonder why devs prefer package managers that abstract OSes.

[Annatar]

I do, because in long term sight their approach is irrational and expensive.
