CONFIRMED WORKING - a great milestone Jude, F***ing good work!
Both keyboard and mouse working without Xorg.conf :-)
When inserting flash memory sticks they get autodetected and device
nodes created :-)
I presume that this is not over devtmpfs, so you know it's vdev.
When I ran previous version of vdev this did not happen
so yes it is this iteration of vdev that does the job :-)
Other parts of my system was not touched when I upgraded :-)
I have no devtmpfs mounted :-)
Thanks for other info!
Question This is working without a value for
/proc/sys/kernel/hotplug so it is not used and
only for udev???
Linux handles hotplug events in multiple ways:
- /proc/sys/kernel/hotplug (aka "hotplug helper"):
On each hotplug event, the kernel starts the hotplug helper with
an appropriate environment.
hotplug, hotplug2, and mdev/smdev use this.
- netlink:
A daemon connects to the kernel and listens for hotplug events.
udev, s6-devd, nldev, and vdev use this.
- devtmpfs:
The kernel maintains a filesystem in RAM containing all devices that
are present, and at hotplug the kernel automatically adds a new device
with default permissions and name.
This can sometimes be used alone; udev and perhaps Android's hotplug
solution rely on this and change the permissions/owners/... after the
fact.
Hopefully that clarifies things for you.
Thanks,
Isaac Dunham
