Mark nbd as inactive until connected (#2422)
Currently, 99-systemd.rules.in contains a line for network block devices, which mark them as inactive until the first change event, and as active from then on forward. This is not correct. A network block device can be connected or disconnected; this state is signalled by the presence or absense of a "pid" file, which contains the PID of the nbd client userspace process that started the connection. Update the rules file so that it checks for the presence of that file to decide what to set SYSTEMD_READY to. Note that current kernels do issue a change event upon connecting the device, but not yet upon disconnecting. While it's possible to wait until that's been fixed, the behaviour of the rule with TEST!="pid" in the absence of a proper uevent is exactly the same as the behaviour of the old rule; so it should be safe to apply now.
