Hi, Hilton!
Thank you for the message, I tried using it in my package definition
```
(define-public my-linux-package
(package
(inherit (customize-linux
#:linux linux-libre
#:defconfig
(local-file "linux-libre-config")))))
```
But unfortunately it didn't work for me
```
error: in phase 'configure': uncaught exception:
misc-error #f "~A ~S" ("Mismatching configurations in .config and
arch/x86/configs/guix_defconfig" (("CONFIG_RTW89" (#f "n"))
("CONFIG_RTW89_CORE" (#f "n")) ("CONFIG_RTW89_PCI" (#f "n"))
("CONFIG_RTW89_8851B" (#f "n")) ("CONFIG_RTW89_8852A" (#f "n"))
("CONFIG_RTW89_8852B_COMMON" (#f "n")) ("CONFIG_RTW89_8852B" (#f "n"))
("CONFIG_RTW89_8852BT" (#f "n")) ("CONFIG_RTW89_8852C" (#f "n"))

("CONFIG_RTW89_8852BTE" (#f "n")) ("CONFIG_RTW89_8852CE" (#f "n"))
("CONFIG_RTW89_8922AE" (#f "n")))) #f
phase `configure' failed after 18.4 seconds
```
Which is strange because if I download the source using "guix build
linux-libre --source", unpack it, put my config and run "make" within
"guix shell --development linux-libre" - it builds the source code
successfully.
I guess, #:defconfig in customize-linux does not use my kernel config
but tries to generate the config using it?
Anyway, it didn't work for me.
So, I guess my question remains - is there a way to use a custom
kernel config to build one?
