Good morning,

Yay!  Thank her for the patch.

-linux-module's better.  The currently random names should 
probably be standardised.

> + (define-public rtl8821ce-linux-module

This can go under the existing rtl8812au-aircrack-ng-linux-module. 
I knew that chip number looked familiar.

This should be 0.0.0 unless there's some 0.0.1 release of which 
I'm unaware.

Git check-outs should have a

 (file-name (git-file-name name version))

field to make the store file name a bit nicer (and easier to 
recognise).

OK, I'm going to add #:make-flags support to l-m-b-s.

If you copied this from rtl8812au-aircrack-ng-linux-module I 
apologise :-)  I (and Guix) prefer specifying the default up-front 
like so:

 (lambda* (#:key (make-flags '()) … #:allow-other-keys) …

Then you can use it without ceremony.

‘driver’

> +      (description "This is Realtek's RTL8821CE Linux driver 
> for wireless

Invisible trailing space.

> +network adapters.")

This ought to be a little longer.  I can throw something together 
if you're without inspiration.

The AUR package says ‘with firmware’, which would be problematic 
if I'd actually found any.  The README also mentions firmware at 
the very end.  Do you know what they mean?  Does this package work 
out of the box with Linux-Libre?  Is that only for Bluetooth?

Kind regards,
