#2Good to see it so far along!
There's some work to be done in rust on portability - it's been a problem in pkgsrc too.

#3Any "Pi'esc" boards available yet? I would love to run Buster on a RISC-V board.
Seeedstudio has an "Arduino'esc" RISC-V board for around USD 30 which looks very interesting. [1]
This board [2] also looks very interesting but is around USD 1000 and I can't find any comparisons on performance to a "regular" PC. I know these things are like comparing apples to oranges but I would like to know how for example a browser performs loading a webpage in comparison with another CPU.
There also appears to be an expansion board with PCI so you can add a GPU for USD 2000. [3]

The Unleashed board has a performance similar to a Raspberry Pi 3 in cpu terms but it's biggest bottleneck is that the SD card is running on a SPI bus where it gets something like 2MB/s. This is due to having the complete SOC as opensource and the SD card association not allowing open source IP for it's interface.

#5Basically LLVM is now a dependency of equal importance to GCC for Debian.
Hopefully this will help motivate expanding architecture-support for LLVM, and by proxy Rust.

#6Looking forward to a standardized MMU interface and page table format.

I think there's some degree of compatibility between SD-card and MMC-card standards, and that the latter are comparatively more open. Surely that could solve the open-IP issue?

Whoa, I had considered the unleashed board to play around with and bookmarked it, but they are not very overt with the price. I didn't realize it was $1000 USD. You have to click through twice to discover it.

It's been a fairly important thing for debian for a while, but this probably solidifies it even more. https://clang.debian.net/

You might consider the HiFive board. It's around 50 dollar, a more appropriate price for something to play around with.
