La variabile DISTDIR definisce la locazione dove Portage salverà il download dell'archivio codice sorgente. Il suo valore predefinito è /var/cache/distfiles.

Questa posizione, nota anche come posizione per i "distfiles", ospita il codice sorgente di tutto il software che viene installato sul sistema (o che si tenta di installare). Dal momento che essa non viene automaticamente ripulita, gli utenti dovrebbero considerare l'uso di strumenti quali eclean-dist (installato come parte del pacchetto app-portage/gentoolkit) per tenere sotto controllo la sua dimensione. Si legga l'articolo su eclean per maggiori dettagli.

Gli utenti possono impostare la variabile DISTDIR in /etc/portage/make.conf:

Attenzione
Beware where you place your DISTDIR! Only trusted users should be granted write access to this location.

File integrity check and unpacking is a non-atomic operation, allowing for an attack where a file is swapped in between, possibly leading to compromise the system.

Source of archives

To download source code archives, Portage will download files from servers defined in the GENTOO_MIRRORS variable first (to alleviate load on upstream project resources and for other reasons). The SRC_URI variable in individual ebuilds, points to the package's original source files, which is originally downloaded by the ebuild maintainers during ebuild creation and development.

Part of ebuild development is the creation of Manifest files, which ensure the upstream source files are not modified from the time they are downloaded by the ebuild developer, distributed to Gentoo's mirror system, then to their destination on the endpoint system.

Bypassing Gentoo mirrors

Attenzione
{{{1}}}

To download the source archives bypassing Gentoo mirrors, set the GENTOO_MIRRORS variable to an empty value from the command-line. For example:

root #GENTOO_MIRRORS="" emerge --ask www-client/firefox
