 Most distributions start as a remastered version of another distribution as evidenced by the announcements made at DistroWatch.Notably, remastering SLS Linux forked Slackware, remastering Red Hat Linux helped fork Yellow Dog Linux and Mandriva and TurboLinux, and by remastering a Debian distribution, Ubuntu was started, which is itself remastered by the Linux Mint team.These might involve critical system software, but the extent of the customizations made in remastering can be as trivial as a change in a default setting of the distribution and subsequent provision to an acquaintance on installation media.
