User:Vazhnov/Knowledge Base:replace rust with rust-bin

It may be desirable to switch from source-based dev-lang/rust to binary-based dev-lang/rust-bin, for example to avoid the compilation time involved in the from-source package.

Note
It is also possible to install dev-lang/rust from the binhost.

Here are the steps to do this:

Install binary-based Rust package:

root #emerge --ask dev-lang/rust-bin

Remove source-based Rust package:

root #emerge --ask --deselect dev-lang/rust

Do a wold upgrade

root #emerge --ask --update --deep @world

Do a final cleanup:

root #emerge --depclean

Optional:

While dev-lang/rust-bin should satisfy any dependencies in ::gentoo, mask dev-lang/rust to prevent it being pulled in again:

root #echo 'dev-lang/rust' >> /etc/portage/package.mask
