In 2010s, idea of an immutable Linux distro began to take shape. Following popularization of containers with rise of Docker, people became interested in Linux, where core system is locked read-only and can only be updated as a whole (atomically) instead of being updated package by package. <a href="https://www.zdnet.com/article/how-red-hat-just-quietly-radically-transformed-enterprise-server-linux/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.zdnet.com/article/how-red-hat-just-quietly-radically-transformed-enterprise-server-linux/</a>

Joel Wirāmu, PaulingUpgraded to <a href="https://cloudisland.nz/tags/rhel10" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rhel10</a> in place using <a href="https://cloudisland.nz/tags/leapp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#leapp</a> on my production server. Everything worked; no issues other than needing to remove epel temporarily during the upgrade. Reminded me that I need to replace the bnx2 10G NICS in that server sooner rather than later.
