Comment 2 for bug 467300

What is the actual use case for making the directory motd.legal-displayed is written to configurable? This seems only to introduce the risk of accidentally displaying the motd multiple times if the target of $XDG_CACHE_HOME changes (or is unset), and as the file is a 0-byte stamp file there should be no concerns about impacting the size of disk backups. Where do you want this file instead of ~/.cache, and why?
