The previous day's Docker image is used as the base for the new one being
built - the image is pulled from Docker Hub, `guix pull` is run inside it,
and a new
image is "committed" (Docker terminology for creating a new image from a
file system snapshot).

BTW, I posted an incorrect internal link - the actual Docker images are
available here if
you'd like to try them out:

The daily Docker images described above.

`guix gc --delete-generations` without a parameter causes all preceding
pull and package generations to be deleted.

Yes,  `guix gc --delete-generations`, `guix gc --collect-garbage`, and
`guix gc --optimize`
are run in the order given. Note that passing a specific amount parameter to
`--collect-garbage` makes no difference.

Indeed. It's clear what's taking up the space, but I don't understand why
it does not get garbage collected:
