Thank you for your advice.

At first it's my first installation of GuixSD. My config.scm is edited at
locale, users, file-systems only from original desktop-config.scm.

My knowladge of guixsd configuration is not enogh to make my own
configuration yet. but my expectation is that I could ajdust system
configuration according to ordinal way of postinstallation.

For instance, locale setting at config.scm is to install additional fonts
according to locale or config of multiboot is that I could edit
/etc/grub.d/40_custom for postinstallation.

Cause of I don't know guixsd way yet.
