That's also what I use. Instead of making modifications to
fs/skeleton/, or completely duplicating that skeleton, my post build
script :
*) Copies some additional files (which I typically store and version
control in board/<mycompany>/<myproduct>)
*) Adjust some files from the skeleton. It does this in a way that
allows to re-run make several times without screwing things. For
example, if I need to add a new line at the end of a file
(like /etc/fstab), I first test that this line hasn't already been
added, in order to avoid duplicates.
This technique has several advantages :
*) You don't change the default skeleton, which would mess things up
next time you upgrade Buildroot ;
*) You don't duplicate the entire default skeleton, which prevents you
from taking advantages of new things in the skeleton if you upgrade
Buildroot ;
*) As the post build script is executed at every 'make' invocation,
you don't have to 'make clean ; make' to see the effect of your post
build script changes.
