Comment (by jeremyfelt):

 Replying to [comment:5 jrf]:
 > ... that doesn't take away anything from my earlier remark that the
 constant `WP_INSTALLING` is not unique enough as it's also used when an
 upgrade is run.

 I haven't run into this scenario myself, but I think you can target an mu-
 plugin for load during an upgrade with `WP_INSTALLING &&
 is_blog_installed()`. This would at least let you know if options were
 available.
