Installazione One click dei pacchetti

Questo standard è solo una bozza/proposta e non è opportuno da implementare in ambiente di sviluppo. Potrebbe essere soggetto a cambiamenti in qualunque momento.

Caso d'uso

Permettere all'utente di installare software in pacchetto(i) da uno o più repository che potrebbero non essere presenti nel sistema.

Scopi

Gli scopi comprendono l'automazione del processo, da parte del gestore dei pacchetti, per l'aggiunta dei repository e l'installazione dei pacchetti.
Gli scopi comprendono la presentazione all'utente di un'interfaccia completa di informazioni sufficienti a comprendere l'automazione del processo.
Gli scopi non comprendono la gestione dei dettagli dei pacchetti, come per esempio le dipendenze.

Requisiti

L'azione deve essere avviata con un singolo clic.
Si dovrebbe poter includere il meccanismo d'avvio del processo in una pagina web.
Si dovrebbe poter includere il meccanismo d'avvio del processo su un supporto fisico per i Produttori Indipendenti di Software (ISV).
Sicurezza (l'utente dovrebbe confermare l'aggiunta dei sorgenti di installazione).
Si dovrebbe poter controllare il rilevamento automatico del tipo di repository.
Si dovrebbe poter includere più mirror assieme.
Si dovrebbe poter avere traduzioni multiple delle stringhe di testo dei programmi.
Si dovrebbe poter avere un bottone o un file (a seconda del mezzo di installazione) su cui fare clic per installare il prodotto (o i prodotti) per ogni versione della distribuzione.
I file non dovrebbero essere troppo grandi per minimizzare il tempo di download (es. traduzioni opzionali).
Dovrebbe essere possibile specificare come risolvere i conflitti frequenti (es. compiz/beryl).

Dipendenze

Non esiste un modo adeguato per identificare univocamente i repository (URL? Hash? ID? )
