Rather than copy the basewiki around everywhere, it should be configured to underlay the main srcdir, and pages be rendered from there if not in the srcdir. This would allow upgrades to add/edit pages in the basewiki. Impementaion will be slightly tricky since currently ikiwiki is hardcoded in many places to look in srcdir for pages. Also, there are possible security attacks in the vein of providing a file ikiwiki would normally skip in the srcdir, and tricking it to processing this file instead of the one from the underlaydir. There are also difficulties related to removing files from the srcdir, and exposing ones from the underlaydir. Will need to make sure that the mtime for the source file is zeroed when the page is removed, and that it then finds the underlay file and treats it as newer.
