[Buildroot] Advice needed on package/customize

[Gordon Smith]

Hello -

I've recently used package/customize to successfully overlay files
into an initramfs kernel image.
However, for two from-scratch buildroot builds in a row,
package/customize has copied ZERO files to the kernel image.

A simple case:

In .config:
    BR2_PACKAGE_CUSTOMIZE=y

In package/customize/source:
    $ ls -lA package/customize/source
    total 4
    -rw-r--r-- 1 gsmith gsmith 0 2009-09-01 02:44 .empty
    -rw-r--r-- 1 gsmith gsmith 7 2009-11-11 16:57 hello.txt

After "make", there is no hello.txt in the kernel image or in
rootfs.i686.initramfs_list.

buildroot version is 2009.08

I'm fairly new to buildroot so any suggestions are welcome.
Thanks

After changing the contents of package/customize/source, did you make a
full rebuild (i.e clean everything and restart the build) ?

If not, then the stamp file $(BUILD_DIR)/.customize already existed, so
the contents of package/customize/source are not copied to the target
directory. If you want to force the reinstallation of customized files
without rebuilding everything, then do 'make customize-clean' and
restart make.

Sincerly,

Thomas

Merci bien for the complete answer.

I found a curiosity in the customize package - root directories are
recursively copies inside existing target directories.

Notice that "etc/hello.txt" in customize becomes "etc/etc/hello.txt"
in initramfs:

$ find package/customize -name hello.txt
package/customize/source/etc/hello.txt
package/customize/source/hello.txt

$ grep hello.txt binaries/lsdtm/rootfs.i686.initramfs_list
file /etc/etc/hello.txt
/home/gsmith/source/buildroot-2009.08-linux-2.6.27/project_build_i686/lsdtm/root/etc/etc/hello.txt
644 0 0
file /hello.txt
/home/gsmith/source/buildroot-2009.08-linux-2.6.27/project_build_i686/lsdtm/root/hello.txt
644 0 0

I modified package/customize/customize.mk as best I could to get it to
handle this:
$ diff customize-0.mk customize.mk
14c14,18
<         cp -af $(CUST_DIR)/$$f $(TARGET_DIR)/$$f; \
---
>         if [ -d $(TARGET_DIR)/$$f ]; then \
>             cp -af $(CUST_DIR)/$$f/* $(TARGET_DIR)/$$f/; \
>         else \
>             cp -af $(CUST_DIR)/$$f $(TARGET_DIR)/$$f; \
>         fi \
