At the time of writing, the stable version of rustc is 1.45.2. Would it make sense to bootstrap stable from 1.42.0 (if that's even possible) first, and then continue to bootstrap beta and nightly as desired? I really just want stable rust on my openbsd machine, as the version in ports or the binary repo on openbsd 6.7 is too old to build some projects.

In order to build beta (or nightly) rust channel, you need the required rustc compiler: here 1.45.0. it is a Rust requirement.

The fact that OpenBSD doesn't provide it in 6.7 -stable is related to the way -stable is done.

You could try to build lang/rust 1.45.2 from -current (the port is self contained, but could use specific part of libc which require -current kernel). It might work (kernel/libc incompatibility exists but aren't too common)
