Mechanism for selectively providing mount information to processes running within operating system partitions
First Claim
1. A machine-implemented method, comprising:
- creating, by an operating system, a plurality of non-global operating system partitions within a global operating system environment provided by the operating system, wherein each non-global operating system partition serves to isolate processes running within that non-global operating system partition from other non-global operating system partitions within the global operating system environment, wherein enforcement of boundaries between the non-global operating system partitions is carried out by the operating system, and wherein the plurality of non-global operating system partitions comprises a particular non-global operating system partition;
maintaining a file system for the particular non-global operating system partition, the file system comprising one or more mounts;
receiving a request from a process running within the particular non-global operating system partition to view information for mounts;
determining that the process is running within the particular non-global operating system partition; and
providing to the process information for only those mounts that are within the file system for the particular non-global operating system partition.

Abstract
A mechanism is disclosed for selectively providing mount information to processes running within operating system partitions. In one implementation, a non-global operating system partition is created within a global operating system environment. A file system is maintained for this non-global partition. This file system comprises zero or more mounts, and may be part of a larger, overall file system. When a process running within the non-global partition requests information pertaining to mounts, a determination is made as to which partition the process is running in. Because the process is running within the non-global partition, only selected information is provided to the process. More specifically, only information pertaining to the mounts that are within the file system maintained for the non-global partition is provided to the process. By doing so, the process is limited to viewing only those mounts that are part of the non-global partition'"'"'s file system.
