Project listing

Release Engineering ("RelEng") is Article description::the official Gentoo project focused on coordinating and improving the creation of official media releases of Gentoo Linux and other Gentoo operating systems. It is also primarily responsible for many of the tools used by the installation process, including Catalyst and genkernel. It was also responsible in the past for the Gentoo Linux Installer (GLI).

Goals

The goals of Release Engineering are to continually improve the quality, timeliness and overall procedures for creating official Gentoo Linux releases, as well as acting as the official coordinators for creating new Gentoo Linux release media. This project is very much focused on ensuring that the initial quality of every official release is as high as possible, and that the "from CD" experience is as positive for as many of our users as possible.

Release security and signing

All release media will have its DIGESTS file signed by one of the Gentoo Linux Release Engineering (releng@gentoo.org) PGP keys listed on this page. The keys are available through the subkeys.pgp.net keyserver. They can be used to verify that the media is, in fact, the media shipped by Release Engineering and not from a potential attacker. You will find more detailed verification instructions in the handbooks for each release.

New keys and changes to existing keys will be announced to the following Gentoo mailing lists: gentoo-dev-announce, gentoo-announce, gentoo-core.

Note
Releases up to and including 2007.0 had PGP signatures directly on top of the files. This required large quantities of disk IO for generation on the servers, and validation on the client side. As such, as of the 2008.0 release, the DIGESTS file is now signed instead, making verification a two-step process, but overall much quicker.
Note
During 2011, the DIGESTS files were also expanded to contain hashes other than SHA1 and MD5, to provide more secure validation.

Obtaining the public key:

user $gpg --keyserver subkeys.pgp.net --recv-keys <key id>

Verify the cryptographic signature:

user $gpg --verify <foo.DIGESTS.asc>

Verify the checksum (at least one of these hashes will exist):

user $sha512sum -c <foo.DIGESTS.asc>
user $sha256sum -c <foo.DIGESTS.asc>
user $sha1sum -c <foo.DIGESTS.asc>
