The Yocto Project provides multiple ways to manage the device
manager (/dev
):
Persistent and Pre-Populated/dev
:
For this case, the /dev
directory
is persistent and the required device nodes are created
during the build.
Use devtmpfs
with a Device Manager:
For this case, the /dev
directory
is provided by the kernel as an in-memory file system and
is automatically populated by the kernel at runtime.
Additional configuration of device nodes is done in user
space by a device manager like
udev
or
busybox-mdev
.
