As the title sais. In emerge messages I have sometimes this message. I know this comes because in kernel config this is set. I would like to disable this option, but I can not find the location in menuconfig where I could disable this option.
if I search for this in menuconfig I will receive this

Per the output, you should find it in the menu Generic Driver Options, which you will find in the menu Device Drivers. However, it may be forced enabled by other choices you have made.

littletux,

Notice that there is no Prompt in the search for FW_LOADER_USER_HELPER.
That tells that its an internal configuration symbol.

You only have control over the things that select it.
Selected by:
Code:
 FW_LOADER_USER_HELPER_FALLBACK [=n] && FW_LOADER [=y] ||
 LEDS_LP55XX_COMMON [=m] && NEW_LEDS [=y] && (LEDS_LP5521 [=m] ||
 LEDS_LP5523 [=m] ||
 LEDS_LP5562 [=m] ||
 LEDS_LP8501 [=m]) ||
 DELL_RBU [=m] && X86 [=y] │

Those conditonals are logically ored together. FW_LOADER_USER_HELPER is selected if any of them are true.

The first one is already false because FW_LOADER_USER_HELPER_FALLBACK [=n]

You need to turn off one or more in
Code:
LEDS_LP55XX_COMMON [=m] && NEW_LEDS [=y] && (LEDS_LP5521 [=m]

and all of
Code:
 LEDS_LP5523 [=m]
 LEDS_LP5562 [=m]
 LEDS_LP8501 [=m]
 DELL_RBU [=m]


The appear to be mostly under
Code:
Device Drivers > LED Support

@NeddySeagoon

Thanks for this explanation.

So next question is can I ignore this message, if I don't wan't disable the LED things?

because the message sais
Code:
 *   CONFIG_FW_LOADER_USER_HELPER:       should not be set. But it is.
 * Please check to make sure these options are set correctly.
 * Failure to do so may cause unexpected problems.


and the last line let me feel bad

littletux,

The userspace firmware loader was removed from udev a long time ago.
I don't know what that option does any more.
