AFAIK, using cron is not possible because the machine (a laptop) is sometimes switched off or suspended. I would expect anacron to run cron jobs at about the same time everyday if possible (i.e. in periods where the machine is up). I don't see why an upgrade of anacron should deviate from that. -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Pascaline project (LIP, ENS-Lyon)
