Mount Points
Creating a ZFS file system is a simple operation, so the number
of file systems per system is likely to be numerous. To cope with this, ZFS
automatically manages mounting and unmounting file systems
without the need to edit the /etc/fstab file. All automatically managed
file sys-
tems are mounted by ZFS at boot time.
By default, file systems are mounted under /path, where path
is the name of the file system in the ZFS namespace. Directories are created
and destroyed as needed.
A file system can also have a mount point set in the mountpoint
property. This directory is created as needed, and ZFS automatically mounts
the file system when the zfs mount -a command is invoked
(without editing /etc/fstab). The mountpoint property can be inherited,
so if
pool/home has a mount point of /export/stuff, then pool/home/user
automatically inherits a mount point of /export/stuff/user.
A file system mountpoint property of none prevents the file
system from being mounted.
If needed, ZFS file systems can also be managed with traditional
tools (mount, umount, /etc/fstab). If a file system's mount point is set to
legacy, ZFS makes no attempt to manage the file system, and the
administrator is responsible for mounting and unmounting the file system.
