1Warning! 2======== 3 4This directory does *not* contain the root filesystem that you can use 5on your embedded system. Since Buildroot does not run as root, it 6cannot create device files and set the permissions and ownership of 7files correctly in this directory to make it usable as a root 8filesystem. 9 10For that reason, do *not* use the contents of this directory to mount 11your root filesystem over NFS or copy the contents of this directory 12to a SD card or USB key, thinking it will work as the root filesystem 13for your embedded system. It will simply *not* work. 14 15Instead, if you need a usable root filesystem, please select one of 16the filesystem image formats available in the Buildroot configuration 17interface (make menuconfig or others) in the "Filesystem images" 18sub-menu. If you want to get a filesystem image that you can easily 19extract to your SD card or to some directory exposed through NFS, 20please use the "tar the root filesystem" option. It will generate a 21images/rootfs.tar image in your Buildroot output directory, which you 22can extract as root: 23 24 sudo tar -C /destination/of/extraction -xf images/rootfs.tar 25 26Those image files are created using the contents of the target/ 27directory, but there is a post-processing step to create device files 28and set ownership/permissions properly even if Buildroot does not run 29as root. 30
