Shameless gentoo plug: gentoo does rolling releases. There&#x27;s still stable v unstable but it&#x27;s per-package. I&#x27;ve run everything unstable for years (except the kernel and default gcc which I update only infrequently). Most packages get updated unstable ebuilds within days of release, probably because with nice upstream choices, a new ebuild can be made with a change on a single line. I&#x27;ve even made such an ebuild myself with no experience when I needed <i>today&#x27;s</i> version.<p>There&#x27;s even a way to make an ebuild for nightlies, although you can get build breaks with those.
