Oh-oh, thanks for your lights.

Hah!

Log excerpts, something that may matter but that I missed at first:
 anacron[22814]: Job `cron.daily' locked by another anacron - skipping

Don't know exactly what went wrong there, but I killed a few processes
and I'll see how it behaves naturally this night, if it still fails I
know have enough to observe, understand and fix. I think you helped me
understanding few things here and how to fix it, thanks, James and Pete!
