8 Ideally we'd just have a repository of binary builds for everything
9 with default USE flags for a few profiles, and users could choose to
10 configure portage to just download the binary package if the flags
11 match, and of course this could be overridden per-package. Then there
12 would be no need for -bin anything. We have to maintain half of that
13 for the stage builds anyway.
15 I don't have a strong preference but I doubt that many of our users
16 receive any benefit whatsoever from building rust from source, and so
17 I'd suggest -bin ought to be the default. However, having a
18 pre-installation notice that the -bin is available with a link/etc to
19 how to use it seems reasonable. I bet a lot of users spend more time
20 getting the source build to work than it would take to just
21 reconfigure things so that they get the -bin. If users are building
22 in a tmpfs or with numerous parallel jobs odds are that they'll end up
23 with a build failure for rust - CPU cores are way cheaper than RAM.
