I've pushed some patches I've been using since ‘forever’ to 
core-updates.  They simply remove the entire right-hand ‘Server’ 
form, and short-circuit the logic behind it that caused the long 
delays.

An older work-around I tried was to simply link to the store 
cupsd.conf in /etc/cups.  This solves the immediate problem, and 
even allows viewing (not editing) a few settings in said form. 
It's an option for those who can't wait for core-updates to be 
merged (don't forget to delete it next year… :-).

However, doing so merely hides the fact that this code is broken 
with -c FILE by effectively circumventing the option in a very 
sneaky way.  A step back, not forward.

Kind regards,

T G-R

Hi, ever since I have started using Guix a few years ago, I have always
found that the cups page at http://127.0.0.1:631/admin load very
slowly, with nothing appearing on the Web browser page for something
like two minutes. The home page (http://127.0.01:631) loads very
quickly, and also other pages you select after you get to the admin
page (e.g., modifying a printer) load quickly. I have had this problem
across multiple Guix computers using different printers. I am wondering
if all CUPS installations in the world have this problem, which seems
unlikely, or if it is something specific to the Guix service
configuration.
This is the cups service entry for my system:
    (service cups-service-type	     (cups-configuration	      (
web-interface? #t)	      (log-level 'debug)	      (access-
log-level 'all)	      (extensions	       (list hplip-minimal
cups-filters))))
