I understand that udev needs or used to need uevent_helper, but I am not clear |
2 |
if I should or should not enable this module in a new kernel I'm rolling. Can |
3 |
you please advise: |

CONFIG_UEVENT_HELPER: |

|

The uevent helper program is forked by the kernel for |
9 |
every uevent. |
10 |
Before the switch to the netlink-based uevent source, this was |
11 |
used to hook hotplug scripts into kernel device events. It |
12 |
usually pointed to a shell script at /sbin/hotplug. |
13 |
This should not be used today, because usual systems create |
14 |
many events at bootup or device discovery in a very short time |
15 |
frame. One forked process per event can create so many processes |
16 |
that it creates a high system load, or on smaller systems |
17 |
it is known to create out-of-memory situations during bootup. |
