So we all know about the file check that runs at boot. It turns out that the "Ctrl-C" that is supposed to skip doesn't, nor does the "S" which it used to be. It seems there is some suggestion this may be due to the theme. Some flavors don't even seem to show the skip option. Anyways, we need to figure this out and get it resolved once and for all so at least users aren't confused. I'd rather have nothing than a suggestion of something that doesn't work.
Thanks to a bunch of testing from others, this works everywhere (all the flavors) but sometimes (especially Lubuntu?) it needs to be hit multiple times for it to work. So maybe something else is going on.
