Comment 11 for bug 1517582

i dont know if it will make sense to run f-k on a UEFI system, i can tell you once we support one ;)

in any case there is a mechanism to make f-k skip all f-k calls ever. that didnt work in your case, which i "fixed" (in quotes because the var lives in three places now, it should be moved into main() in the functions file instead to have the code snippet only once in a more central place)

if you want to unseed it instead of using the established skip mechanism i think thats reasonable and a lot cleaner but will also require a bit more work :)
disabling a whole class of devices is IMHO not the way to go here (imagine UEFI systems that store kernel/initrd in encrypted MTD devices etc ... ) lets not make the life of porters harder.
