Hi,

The Arch Linux community recently started a discussion around adopting
SPDX license identifiers to simplify/improve their license handling:

https://lists.archlinux.org/pipermail/arch-dev-public/2019-October/029695.html

I imagine that the SPDX community may be interested in chiming in if
there are any known pitfalls on doing so, or general advice around it.

Cheers!
