Hollis, All,

On 2015-08-11 17:11 -0700, Hollis Blanchard spake thusly:
> Some fine version control systems make all files read-only. The custom DTS file
> may therefore be read-only, and that permission is preserved when copying into
> the Linux build directory. A subsequent rebuild tries to 'cp' again, which
> fails with a "Permission denied" error unless the -f option is used.
