There are several ways to do it:
http://buildroot.uclibc.org/downloads/manual/manual.html#_customizing_the_generated_target_filesystem
Using the "customize" package is depricated, and I think will be
eliminated in the near future. It sounds to me like you probably want
to define a post-build script that merges your custom files files into
the target tree after it's been built.
I've placed a tree of files to be merged in "../custom-files" and the
post-build script copies them into the target directory. My
post-build script shown below. The line the does the merging of my
custom files is the 'tar' command. The rest of the script tweaks some
of the pre-existing files.
Once you've written a post-build script, you need to set the the
BR2_ROOTFS_POST_BUILD_SCRIPT configuration variable to point to it:
In my .config file:
BR2_ROOTFS_POST_BUILD_SCRIPT="../postbuild.sh"
------------------------------postbuild.sh------------------------------
#/bin/bash
echo ">>> Post-build script start"
TARGET="$1"
set -x
# modify snmpd init script so that it listens on all interfaces rather
# than only on 127.0.0.1
sed -i '/^SNMPDOPTS/ s/ *127\.0\.0\.1//g' $TARGET/etc/init.d/S*snmpd
# copy custom-files
tar -c -f - -C ../custom-files --exclude-vcs --exclude-backup . | \
tar -v -x -f - -C "$TARGET"
# set some global env variables by exporting them in rcS
sed -i -e '/^export PATH=/ d' $TARGET/etc/init.d/rcS
sed -i -e '/^export LD_LIBRARY_PATH=/ d' $TARGET/etc/init.d/rcS
sed -i -e '2 iexport PATH=$PATH:/apps/bin' $TARGET/etc/init.d/rcS
sed -i -e '2 iexport LD_LIBRARY_PATH=/apps/lib' $TARGET/etc/init.d/rcS
# tweak PHP settings
sed -i -e 's/^upload_max_filesize.*/upload_max_filesize = 10M/g' $TARGET/etc/php.ini
# make sure ssh keys aren't readable by anybody except owner
chmod go-rwx $TARGET/etc/ssh_*_key
set +x
echo ">>> Post-build script done"
