As a consequence of the unavailability of binaries on our machines, you
ended up building webkitgtk and probably other packages.  Building
webkitgtk requires a lot of resources, in particular more than 4G or
RAM, so this can easily run out of memory.

Again the goal is to avoid this situation altogether, so I don’t think
we should ask users to systematically add a swap partition before they
start ‘guix system init’.

Thanks for your feedback,
