What does this actually mean? Can we more clearly document the negatives?
Is it that Rust takes a long time to build? This seems like just a
consequence of a sourced based distribution. Many things take a long
time to build. I suspect rust is not the only package and again we are
back to staffing binhost like projects for much of the tree so that
this particular complaint can be mitigated, not just for rust, but for
any package.
Is it that Rust build fails because users lack the resources to build
it? We should be using check-reqs here to detect this pre-build and
give the user choices (like telling them rust can't be compiled from
source on their machine and to use rust-bin.)
I tend to empathize more with Peter Böhm later in the thread, in that
Gentoo is sourced based and I'd expect portage to be installing things
from source by default. Building from source is resource intensive and
expensive, yes. I think if you want a binary-based distro you are
using the wrong distro at the moment.
