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.
