Stefano Marinelli<p>I've never hidden my admiration for <a href="https://mastodon.bsd.cafe/tags/illumos" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>illumos</span></a>-based systems. I have a few setups based on <a href="https://mastodon.bsd.cafe/tags/OmniOS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OmniOS</span></a> and <a href="https://mastodon.bsd.cafe/tags/SmartOS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SmartOS</span></a>, and they're solid as a rock. I like them both: OmniOS is more "malleable", while SmartOS is more of a hypervisor like <a href="https://mastodon.bsd.cafe/tags/xcp" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>xcp</span></a>-ng or <a href="https://mastodon.bsd.cafe/tags/xen" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>xen</span></a> - meaning you install it on the host and delegate everything else to the zones.</p><p>I also love <a href="https://mastodon.bsd.cafe/tags/FreeBSD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>FreeBSD</span></a> jails, but zones sometimes cover use cases that jails can't (and vice versa). For example, imposing RAM limits in jails works, but it effectively "denies more ram" to a process when it requests more memory. The end user doesn't see this directly. On illumos, the user sees everything. I have some `lx` zones with Debian and Virtualmin, and users have never noticed that they aren't really on <a href="https://mastodon.bsd.cafe/tags/Linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Linux</span></a>. A free or top will show only the assigned RAM.</p><p>And that's one of the biggest problems with open-source operating systems: they all have something good, and I always feel the urge to use them all! 🙂</p><p><a href="https://mastodon.bsd.cafe/tags/OpenSource" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OpenSource</span></a> <a href="https://mastodon.bsd.cafe/tags/IT" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>IT</span></a> <a href="https://mastodon.bsd.cafe/tags/SysAdmin" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SysAdmin</span></a></p>
