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.

# This macro properly escapes a command string, then prints it with printf:
|
||||
#
|
||||
# - first, backslash '\' are self-escaped, so that they do not escape
|
||||
# the following char and so that printf properly outputs a backslash;
|
||||
#
|
||||
# - next, single quotes are escaped by closing an existing one, adding
|
||||
# an escaped one, and re-openning a new one (see below for the reason);
|
||||
#
|
||||
# - then '%' signs are self-escaped so that the printf does not interpret
|
||||
# them as a format specifier, in case the variable contains an actual
|
||||
# printf with a format;
|
||||
#
|
||||
# - finally, $(sep) is replaced with the literal '\n' so that make does
|
||||
# not break on the so-expanded variable, but so that the printf does
|
||||
# correctly output an LF.
|
||||
#
|
||||
# Note: this must be escaped in this order to avoid over-escaping the
|
||||
# previously escaped elements.
|
||||
#
|
||||
# Once everything has been escaped, it is passed between single quotes
|
||||
# (that's why the single-quotes are escaped they way they are, above,
|
||||
# and why the dollar sign is not escaped) to printf(1). A trailing
|
||||
# newline is apended, too.
