Hi all,

is there a way to be notified when a mount occurs on the system ?
Have you looked on google? The link is a bit misleading but they do
give a way to do it (not using inotify).

Thanks a lot for the pointer. I am not sure this solution will work, because it is inadequate for watching a specific location in a container context separated by the mount and the network namespaces. We have multiple mount points at the same place (eg. the mount point inheritance, the container configuration and the init scripts may mount /dev or /var/run several time) and the network namespace separation will make impossible to watch udev event via a netlink socket. I didn't look at the inotify implementation but IMHO, it should be worth to add IN_MOUNT and IN_UNMOUNT events for inotify no ?
