&gt; It&#x27;s just in the same bag as Gentoo regarding release process.<p>There&#x27;s a big difference, though - Arch Linux has no concept of partial upgrades. You <i>have</i> to update, or things break. Gentoo allows you to stick with old versions and has a pretty sophisticated mechanism for that (&quot;slots&quot;). It&#x27;s also complicated, which is one of the reasons Arch Linux is easier to use.<p>This makes Arch Linux unsuitable for pretty much any &quot;production&quot; scenario. Puppet version updated to 4? Tough luck if you didn&#x27;t scramble and update all of your code since version 4 has backwards-incompatible changes.<p>Works pretty well for desktops - if something breaks, you can usually just fix it. But it does not scale.<p>Gentoo, on the other hand, has an unstable and a &quot;stable&quot; channel and you can use it for production systems if you&#x27;ve got the necessary manpower to essentially build your own distro.
