Custom font on the console

[Cristiano Fagnoli <cristianof6@gmail.com>]

Hi to all,

I just started to use guix system, and i'm trying to get used to it; very
first start.

I always use the text console on laptop so i have a little problem setting
a custom font for the console considering the display resolution is
1920x1080 and the default characters are very small to see.

I already read a previuos similar question on this mailing list and i
copied the piece of code for changing the font in the system configuration.

But when i reconfigure i get error and i cannot proceed further.

my config.scm is detailed below and the specific lines of code that gives
error (invalid field specifier) are delimited by the comment " COPIED FROM
MAILING LIST SUGGESTION"

Thank you in advance
