I am making some use of posix messages queues, and in order to interactively view/manipulate these queues on my Debian squeeze system it is necessary, as described in mq_overview(7), in to manually: mkdir /dev/mqueue mount -t mqueue none /dev/mqueue after each boot
I am looking for the best way to make this automatic, and as /dev/shm is already being automatically mounted to give access posix semaphores and shared memory, it seems logical and consistent to mount mqueue the same way... There appears to be a line D shm /etc/udev/links.conf, to create the mount point which suggests that a similar entry for mqueue would be appropriate, although the comment at the top of the file suggests that its use is discouraged. The alternative of /lib/udev/devices suggested in the comment does not seem appropriate as what is being created is a directory (mount point), not a device.... There also appears to be a line to create the mount point 'shm' if it doesn't already exist (and then mount it) in /etc/init.d/mountdevsubfs.sh, plus an unmounting command in /etc/init.d/udev. Then again, I can't see any reason why the mounting couldn't be handled a little more intuitively by adding an entry to /etc/fstab... Does anyone know if there is a reason why shm is mounted by default and mqueue is not? Is there any consensus on the best way to have this filesystem mounted on boot? DigbyT
