What is mount namespace in Linux?
Mount namespaces provide isolation of the list of mounts seen by the processes in each namespace instance. Thus, the processes in each of the mount namespace instances will see distinct single- directory hierarchies. A new mount namespace is created using either clone(2) or unshare(2) with the CLONE_NEWNS flag.
What is mount namespace separation?
A mount namespace is the set of filesystem mounts that are visible to a process. It makes it so that the superuser has separate mount points visible to it from the rest of the system/apps. I believe the intention is to prevent any issues when remounting partitions, such as remounting /system as read-write.
What is a mount namespace?
A mount namespace is the set of filesystem mounts that are visible to a process. From clone man page : Every process lives in a mount namespace. The namespace of a process is the data (the set of mounts) describing the file hierarchy as seen by that process.
What is namespace mode?

How to create a new mount namespace in Linux?
A new mount namespace is created using either clone (2) or unshare (2) with the CLONE_NEWNS flag. When a new mount namespace is created, its mount point list is initialized as follows: * If the namespace is created using clone (2), the mount point list of the child’s namespace is a copy of the mount point list in the parent’s namespace.
How many types of namespaces are there in Linux?
A Linux namespace is an abstraction over resources in the operating system. We can think of a namespace as a box. Inside this box are these system resources, which ones exactly depend on the box’s (namespace’s) type. There are currently 7 types of namespaces Cgroup, IPC, Network, Mount, PID, User, UTS.
How does UNshare ( 2 ) work with mount namespaces?
(The unshare (2) CLONE_NEWNS operation brings across all of the mounts from the original mount namespace as a single unit, and recursive mounts that propagate between mount namespaces propagate as a single unit.)
What are the different types of namespaces in cgroup?
There are currently 7 types of namespaces Cgroup, IPC, Network, Mount, PID, User, UTS. For instance, the Network namespace encapsulates system resources related to networking such as network interfaces (e.g wlan0, eth0 ), route tables etc, the Mount namespace encapsulates files and directories in the system, PID contains process IDs and so on.
