Creating new ZFS filesystems may seem strange at first since they are initially mounted under their parent filesystem. This is no problem since ZFS provides a simple and powerful mechanism for setting the mount point for a filesystem.
To change the mount point of the filesystem techrx/logs to /var/logs, you must first create the mount point (just mkdir a directory) if it does not exist, and then use the zfs command:
mkdir /var/logs
zfs set mountpoint=/var/logs techrx/logs
The filesystem will be unmounted (as long as you are not currently in that filesystem) and remounted as /var/logs.
One great consequence of this design is that a huge pool can be created (multi-volume mirror or raidz or a SAN lun, etc.) and as many filesystems as you can imagine created in that pool. These filesystems can then be mounted anywhere in the system that you want.
