Warning!

|
========
|
|
|
|
This directory does *not* contain the root filesystem that you can use
|
|
on your embedded system. Since Buildroot does not run as root, it
|
|
cannot create device files and set the permissions and ownership of
|
|
files correctly in this directory to make it usable as a root
|
|
filesystem.
|
|
|
|
For that reason, do *not* use the contents of this directory to mount
|
|
your root filesystem over NFS or copy the contents of this directory
|
|
to a SD card or USB key, thinking it will work as the root filesystem
|
|
for your embedded system. It will simply *not* work.
|
|
|
|
Instead, if you need a usable root filesystem, please select one of
|
|
the filesystem image formats available in the Buildroot configuration
|
|
interface (make menuconfig or others) in the "Filesystem images"
|
|
sub-menu. If you want to get a filesystem image that you can easily
|
|
extract to your SD card or to some directory exposed through NFS,
|
|
please use the "tar the root filesystem" option. It will generate a
|
|
images/rootfs.tar image in your Buildroot output directory, which you
|
|
can extract as root:
|
|
|
|
sudo tar -C /destination/of/extraction -xf images/rootfs.tar
|
|
|
|
Those image files are created using the contents of the target/
|
|
directory, but there is a post-processing step to create device files
|
|
and set ownership/permissions properly even if Buildroot does not run
|
|
as root.
