I probably should've asked for help here earlier, the first commit of
guix in the overlay was probably some time back in january, but only now
you do no longer require the workarounds for outdated guile on gentoo we
had, so less annoyance if you don't run many test VMs.

The disfunctional thing currently is:

guixbuilder01 ... guixbuilder10 get created and added to guixbuild
group.

Post-setup I let root authorize hydra's pubkey, then I run
`rc-service start guix' which sadly makes the terminal unusable if you
don't append "&".

running guix pull then as root downloads happen, but as soon as builder
should start, it fails:

shikahr ~ # guix pull

          shikahr ~ # id -nG guixbuilder1
          id: guixbuilder1: no such user
          

I know the openrc service is total crap because if you don't kill every
instance of guix-daemon before shutdown/reboot, you have almost 30
minutes delay.
OpenRC services are not my favorit thing to write, but it should just
work.

Also strange enough a sequence from 1 - 10 in ebuild creates users 01 -
10.
