Górny: Gentoo: profiles and keywords rather than releases
Gentoo developer Michał Górny has written a lengthy <a href="https://blogs.gentoo.org/mgorny/2024/08/20/gentoo-profiles-and-keywords-rather-than-releases/" rel="nofollow">blog
post</a> that explains how Gentoo approaches releases:
Gentoo is something of a hybrid, as it combines the best of both
worlds. It is a rolling release distribution with a single shared
repository that is available to all users. However, within this
repository we use a keywording system to provide a choice between
stable and testing packages, to facilitate both production and
development systems (with some extra flexibility), and versioned
profiles to tackle major lock-step upgrades.
