For some reason I thought that the first log you've sent is daemon log. It wasn't and in fact I'd like to see it for the case where you mount /dev/mqueue and enable the namespace (=undo the workaround). > > BTW, can you help me to understand how can you make this [1] work if it’s /dev/mqueue. > As far as I know /dev/mqueue is not a block device, how can we mount /dev/mqueue to somewhere ? A filesystem doesn't have to be backed by a block device in order to be mountable. tmpfs is a great example. mqueue is yet another one of such filesystems. BTW: $ grep nodev /proc/filesystems Looks like there's a lot of nodev filesystems.
