Colin, I sent this last evening, but I haven't seen it on-list.   For
some reason a fair number of my messages don't get through.  Could it
be that the digital signing worries the filters?

Agreed.  Adding nofail makes no difference.  I've also tried removing
all options, down to a minimum defaults.  However, they shouldn't stop
boot.  FWIW, I'm still seeing that message about a dependency failure
for remote file systems.

No, gdm doesn't get that far either.
