This is a primitive unit file for systemd.

For now, it is for small embedded systems, with a shared key: /key.pub.

We welcome improvements.

It is likely just pkg-ed in initramfs per PR description ("small embedded system"), so the bot seems to have hallucinated that this is a regular go cmd to be go install-ed (?)

yeah, the env part seems like it's assuming a regular distro that has /usr/bin/env, which u-root might not have. btw, i think this might not be for u-root either. from talking with ron on the side, i thought this was just some random distribution.

that said, it's not wrong about the discrepancy between saying "cpud just needs to be in $PATH" and hardcoding /usr/bin/cpud.

systemd requires absolute paths (i think), so you have to make some assumption: either about the existence of /usr/bin/env or the location of cpud. either way is fine with me.
