You can interact with the daemon:

  cd /path/to/guix/root
  sudo mount --bind /dev dev
  sudo mount --bind /proc proc
  sudo mount --bind /sys sys
  sudo unshare -m sudo chroot . /run/current-system/profile/bin/bash
  source /etc/profile

  guix-daemon --build-users-group=guixbuild &

If you then `su` to a plain user, do `source /etc/profile` again.

I think all of `guix pull`. `reconfigure` and `package` search, install 
and update worked here with that approach. `guix download` failed due to 
nss certificates, until I added:
  export SSL_CERT_DIR="$HOME/.guix-profile/etc/ssl/certs"
  export 
SSL_CERT_FILE="$HOME/.guix-profile/etc/ssl/certs/ca-certificates.crt"
  export GIT_SSL_CAINFO="$SSL_CERT_FILE"
