That’s indeed the solution: checked my kernel config and found the “old” method.
I swapped to the modern method and rebuilt de kernel.  The system now looks for 
/dev/sdx devices.

My “old” config was created, following the book’s instruction (Linux From 
Scratch - Version 7.7-systemd, page 228):

“A good starting place for setting up the kernel configuration is to run make 
defconfig. This will set the base
configuration to a good state that takes your current system architecture into 
account.”

BTW: the book says also to check:

Processor type and features --->
[*] Enable seccomp to safely compute untrusted bytecode [CONFIG_SECCOMP]
(…)
Firmware Drivers --->
[*] Export DMI identification via sysfs to userspace [CONFIG_DMIID]

The first one is actually under “Kernel options” in de menuconfig; I couldn’t 
find the second one.
