There may be other unforeseen breakage primarily in the handbook portion of the wiki.
The Table Of Contents section of each "PC-BSD® Users Handbook" page may be the best workaround.
Talk:PBI Module Builder Guide
Cannot be deleted/should not be moved/must have redirect
This wiki page is referenced by the pbi_makeport manpage.
Due to this phenomenon, it may be a good idea to have a standard construct or warning. Whether it is solely used for those who edit the wiki, or could be viewed by all, matters little (if it appears professional). The above does not refer to the "talk:PBI Module Builder Guide" page.
