Do something like

    (installer-program #:dry-run? #t)
    ,build $1
    =&gt;
    "/gnu/store/...-installer-program"

and run

    /gnu/store/...-installer-program

* gnu/installer/newt.scm (locale-page): Add #:dry-run? parameter.
(keymap-page): Likewise.
* gnu/installer/newt/keymap.scm (run-keymap-page): Likewise.
* gnu/installer/steps.scm (run-installer-steps): Likewise.  Use it to skip
writing to socket.
* gnu/installer/newt/final.scm (run-final-page): Rename to...
(run-final-page-install): ...this.
(dry-run-final-page, run-final-page): New procedures.
* gnu/installer/parted.scm (bootloader-configuration): Cater for empty user
partitions.
* gnu/installer/utils.scm (dry-run-command): New procedure.
* gnu/installer.scm (compute-locale-step): Add #:dry-run? parameter.  Use it
to avoid actually applying locale.
(compute-keymap-step): Add dry-run? parameter.  Pass it to
keymap-page.
(installer-program): Add #:dry-run? parameter.  If #:true
avoid writing to /proc, use dry-run-command, skip sync and reboot, and pass
dry-run? to...
(installer-steps): ...here.  Add #:dry-run? parameter.  Use it to disable
skip network, substitutes, partitioning pages, and pass it to...
compute-locale-step, compute-keymap-step, and final-page.
