getuto

getuto (Gentoo trust tool) is a tool to maintain a gpg keyring in /etc/portage/gnupg for binary packages:

• It creates a keyring in /etc/portage/gnupg if it doesn't already exist;
• If a keyring already exists, it will refresh the keys from keyservers/wkd and import newer keys if available on the system.

A fresh keyring is needed to safely verify binary packages for revocations and renewals of gpg keys.

If --getbinpkg or --getbinpkgonly is used, Portage will run getuto before fetching any binary packages. It is unused otherwise.

To disable getuto, set PORTAGE_TRUST_HELPER=true in /etc/portage/make.conf.
