 |
|
Hi
I am configuring Kernel 2.6.24, and there is an option under "Generic Driver options" which asks for the path to uevent helper with the default path "/sbin/hotplug"
I don't have /sbin/hotplug. What is supposed to go there?
Thanks in advance!

Thanks, but I don't even have an /etc/hotplug.d which is referenced in your script... Isn't hotplug outdated?

Do you have hotplug installed? Here are my installed hotplug packages:
| Code: | # equery list -i hotplug
[ Searching for package 'hotplug' in all categories among: ]
* installed packages
[I--] [ ] sys-apps/hotplug-20040923-r2 (0)
[I--] [ ] sys-apps/hotplug-base-20040401 (0) |
Both packages are more than 3 years old, I'd call this outdated  |

From: http://www.kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.23-git3.log
| Quote: | Driver core: add CONFIG_UEVENT_HELPER_PATH
The kernel creates a process for every event that is send, even when
there is no binary it could execute. We are needlessly creating around
200-300 failing processes during early bootup, until we have the chance
to disable it from userspace.
This change allows us to disable /sbin/hotplug entirely, if you want to,
by setting UEVENT_HELPER_PATH="" in the kernel config. |
If you don't have /sbin/hotplug, set this to "" to keep the kernel from pointlessly trying to execute it. |

Just curious...I'm in the process of upgrading to 2.6.24 and came across this post. I had to manually edit .config to set UEVENT_HELPER_PATH to "", as "make oldconfig" defaults to /sbin/hotplug. Just out of curiosity...is there a way to specify an empty string during make oldconfig when it wants to default to some value?
