The kernel should not create the lock file, it is the program that should do that, ie modem-manager. Creating the lock file lets other programs that want to use the same serial port know that the port is in use. This file makes it also easy to identify the program using the port.
I guess this is some kind of feature request concerning modem-manager, or maybe a bug because it connects automatically to serial ports without permission of the user. -- ftdi usb serial node only accessible by root https://bugs.launchpad.net/bugs/662881 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
