[bug#30629] [PATCH 0/5] Detect missing modules in the initrd

[Danny Milosavljevic]

Hmm...

$ make TESTS=iso-image-installer check-system

   592:17  1 (map1 ("iso9660" "isofs" "overlay"))

(It's called "isofs" but there are aliases in modules.alias: fs-iso9660, 
iso9960)

I think now we need to take care about the module key resolution order with 
modules.alias, modules.builtin and modules.dep.
