The check for initrd-modules does not appear to handle when loaded
modules use underscores (e.g. "sdhci_of_arasan") but the on-disk modules
use dashes (e.g. "sdhci-of-arasan"). Some modules even use a mix of
underscores and dashes, just to keep it interesting.
The workaround is to use --skip-checks, but this may skip other
important checks.
Putting the "sdhci_of_arasan" in my system config, it fails because it
cannot find the kernel module on-disk by that name.
Ideally, it would find some way of mapping the loaded module names to
the on-disk module filenames, and detect appropriately, ideally
allowing either the on-disk filename or the loaded module name in the
config.
In my config:
(initrd-modules (append (list ... "sdhci-of-arasan" ... )
%base-initrd-modules))
When I run:
$ sudo -E guix system reconfigure /etc/config.scm
<unknown location>: error: you may need these modules in the initrd for
/dev/mmcblk1p1: sdhci_of_arasan
hint: Try adding them to the `initrd-modules' field of your
`operating-system' declaration, along these
lines:
(operating-system
;; ...
(initrd-modules (append (list "sdhci_of_arasan")
%base-initrd-modules)))
Since the on-disk module name uses "-" instead of underscores:
$ find /gnu/store/*linux-libre* -name '*'arasan.ko
/gnu/store/nilzipm6fpicvlzfv1w8yj1j8mm1xlan-linux-libre-4.16.11/lib/modules/4.16.11-gnu/kernel/drivers/mmc/host/sdhci-of-arasan.ko
But the loaded module uses "_" in the name:
$ lsmod | grep arasan
sdhci_of_arasan 20480 1
cqhci 24576 1 sdhci_of_arasan
sdhci_pltfm 16384 1 sdhci_of_arasan
sdhci 61440 2 sdhci_pltfm,sdhci_of_arasan
