Re: Remember when...
Unfortunately, though, most free and open source OSs don't have a regular release cycle or sensible system for releasing patches either.
Picking a few at random, and searching:
Fedora:
Release Cycle / Patch Management
Ubuntu:
Release Cycle / Patch Management
Debian:
Release Cycle / Patch Management
FreeBSD: Release Cycle / Patch Management
So which "most free and open source OSs" are you talking about, specifically?
