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/gnupgif 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.
