Generally, the file systems mounted in a zone include the following:
The set of file systems mounted when the virtual platform is initialized
The set of file systems mounted from within the application environment itself
This can include, for example, the following file systems:
File systems specified in a zone's /etc/vfstab file
AutoFS and AutoFS-triggered mounts
Mounts explicitly performed by a zone administrator
Certain restrictions are placed on mounts performed from within the application environment. These restrictions prevent the zone administrator from denying service to the rest of the system, or otherwise negatively impacting other zones.
There are security restrictions associated with mounting certain file systems from within a zone. Other file systems exhibit special behavior when mounted in a zone. See File Systems and Non-Global Zones for more information.
