runqemu-internal: get rid of annoying but harmless error message
If tap0 interface has been created by other users on the system, we would get error messages when using runqemu. Error messages are like below. Acquiring lockfile for tap0... touch: cannot touch ‘/tmp/qemu-tap-locks/tap0.lock’: Permission denied /buildarea2/chenqi/poky/scripts/runqemu-internal: line 139: /tmp/qemu-tap-locks/tap0.lock: Permission denied flock: 8: Bad file descriptor The system can still boot up because runqemu would try to create a new tap interface. So the error message above is harmless, yet somewhat annoying. This patch fixes the above problem. With this patch, the output would be as follows. Acquiring lockfile for tap0... Acquiring lockfile for /tmp/qemu-tap-locks/tap0.lock failed Setting up tap interface under sudo Acquiring lockfile for tap1... Running qemu-system-arm...
