What I'm saying is that a reload may not even be needed. Well, I'm not sure. But for instance, if /etc/resolv.conf changes (with new DNS servers), I hope that the user doesn't have to restart his web browser, for instance. I've tried with lynx, and strace tells me that /etc/resolv.conf is reread for every new hostname resolution. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
