This particular one could be a bug in the kernel. But the access time (or modification time) is correct here with /dev/pts/* devices, though "w" gives an incorrect idle time. Another issue is that "w" does not output TTY information for me (that's bug 1080335). -- 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)
