makedevs vs. device_table-minimal.txt

[Andrea Adami]

Hello,

after commit 66aa4ed9410ba1d652e40571f48a985337e56a26
(device_table-minimal.txt: fix input device nodes path. Input event
device nodes are usually under /dev/input.) in /dev of my rootfs I
don't have any event device node.

Any obvious reason why makedevs would fail to create /dev/input/eventX ?

Regards

Andrea

Please note that this is linux-kexecboot initramfs, not common image rootfs.
We have no device manager (udev/mdev) there.
And (as I understand image.bbclass) there is no possibility to create 
directory in rootfs from recipe before makedevs call.

I think I know why: the directory must be explicited in the device table file:

++# Input stuff
++/dev/input d 755 0 0 - - - - -
+/dev/input/event c 660 0 0 13 64 0 1 8

I'll test later.

Since you're on >2.6.31, why not use devtmpfs?

Unfortunately not all machines are yet ready for 2.6.3x
Neverthless, there is a bug in the device tables having nodes in
subdirs without creating those.
