>> ArchLinux-style rather thsn NixOS style. Just roll the updates when they are ready into your very own test, int, acc, and finally prod.

The issue is that a rolling-release approach does not have stability guarantees and forces everything to be upgrading all the time.

This does not work very well if you have specialized hardware or scientific equipment. If the drivers for your lab equipment work with a given release of an enterprise linux, you can't just jump on the next release until you have working drivers ready.

The same is true if you are working with some enterprise software which is only certified to work with a given release of an enterprise linux. Would you really want to run business critical software on a version of the operating system which is not (yet) supported by the vendor?
