A Unixban mindennek megvan a helye, \u00edgy a konfigur\u00e1ci\u00f3s \u00e1llom\u00e1nyok is m\u00e1r t\u00f6bb, mint 40 \u00e9ve a \u201efutottak m\u00e9g\u201d kateg\u00f3ri\u00e1ban vannak, konkr\u00e9tan az \u201eetc\u201d nev\u0171 mapp\u00e1ban. Ezek konvencion\u00e1lis text \u00e1llom\u00e1nyok, ez\u00e9rt a rendszergazd\u00e1nak k\u00fcl\u00f6n\u00f6sen \u00fcgyelnie kell, nehogy a rendszert \u00e1tkonfigur\u00e1lja. Egyszer\u0171en megfogalmazva: \u201eetc\/config.conf.bak\u201d \u00e9s t\u00e1rsai, vagy struktur\u00e1ltan haszn\u00e1lva a RCS verzi\u00f3 ellen\u0151rz\u0151 rendszer.<\/p>\n

Ugyanez jobban \u00e9s egyszer\u0171bben el\u00e9rhet\u0151 az etckeeper<\/i>-rel, Joey Hess eszk\u00f6z\u00e9vel, ami automatikusan kifinomultabb verzi\u00f3 ellen\u0151rz\u0151 rendszereket (Version Controll System \u2013 VCS), mint a git<\/i>, mercurial<\/i>, vagy baza<\/i>a<\/i>r<\/i> alkalmaz, megtartja a v\u00e1ltoz\u00e1sokat a konfigur\u00e1ci\u00f3s k\u00f6nyvt\u00e1rban. Telep\u00edt\u00e9s ut\u00e1n el\u0151sz\u00f6r inicializ\u00e1lja a t\u00e1rol\u00f3t:
\n# cd \/etc<\/code>
\n# etckeeper init<\/code>
\nA haszn\u00e1lt VCS enged a \/etc\/etckeeper\/etckeeper.conf-ban v\u00e1ltoztatni, mik\u00f6zben a k\u00fcl\u00f6nf\u00e9le VCS-ek valamif\u00e9le \u201ebzr\u201d-re vagy \u201ehg\u201d-re v\u00e1ltoztatj\u00e1k. Az alap\u00e9rtelmezett be\u00e1ll\u00edt\u00e1s Debianban git<\/i>, Ubuntuban bazaar<\/i>.<\/p>\n

A Debian \u00e9s Ubuntu rendszerekhez install\u00e1l\u00e1skor az apt<\/i> csomagkezel\u0151 rendszer egy kiindul\u00f3 pontot helyez el, amivel az \u00fajonnan telep\u00edtett csomagok konfigur\u00e1ci\u00f3s f\u00e1jlai automatikusan VCS kontrol al\u00e1 ker\u00fclnek. Az \u201eAVOID_DAILY_AUTOCOMMITS<\/span>\u201d v\u00e1ltoz\u00f3val kapcsolhat\u00f3 (pontosabban annak kikapcsol\u00e1s\u00e1val: a ford.<\/em>), hogy az etckeeper<\/i> naponta egyszer \u00e1temelje a v\u00e1ltoz\u00e1sokat. Ellenkez\u0151 esetben sz\u00fcks\u00e9ges a saj\u00e1t v\u00e1ltoztat\u00e1sokat, c\u00e9lszer\u0171en megjegyz\u00e9sekkel, manu\u00e1lisan t\u00e1rolni. Az etckeeper<\/i>-nek k\u00f6sz\u00f6nhet\u0151en nem kell a VCS szintaxis\u00e1val f\u00e1radozni, mivel ezzel az eszk\u00f6zzel k\u00f6zvetlen\u00fcl is megtehet\u0151, p\u00e9ld\u00e1ul
