To Artifact [e4d70e3876]:

• File www/containers.md — part of check-in [da545c9e79] at 2023-01-17 06:29:56 on branch trunk — Removed use of UPX in the container build process. It complicates the build for a tiny gain while breaking ARM builds. We worked around the ARM-on-ARM case earlier, but it also breaks x86 cross-compilation on ARM. Images are already compressed, and while `upx -9` is stronger compression than whatever Docker Engine is using, it's a small advantage. This does mean the static executable isn't compressed any more on x86, but if you want that, you can UPX it afterward. (user: wyoung size: 44247)

The resulting binary is the single largest file inside that container,
at about 4 MiB. (It’s built stripped and packed with [UPX].)
at about 6 MiB. (It’s built stripped.)
