No, the conflict happens because you don't tell ptxdist what you want. Your
directory has special permissions and ptxdist should not ignore that.
If you don't care about the directory permissions, then don't use
install_tree. Install the individual files with install_copy.

In general, 'just add a file to a directory' is not possible. There is no
way to tell opkg if the permissions of a directory are important or not.

The only way to _always_ get the correct permissions is to use 0755 when we
don't care and explicitly handle anything else in _all_ packages that touch
the relevant paths.
