Solaris maintains two sets of share properties: one set for shares that are established at boot time, and another set for shares that are established after boot.
Ideally, these two sets of properties should be synchronized. However, it may be useful in some cases -- for example, when establishing temporary shares -- to maintain two different sets of properties.
Note: On rare occasions, a set of At Boot properties may become invalid. This can occur, for example, if a share is defined At Boot with the WebNFS option disabled, but is then mounted At Boot with the WebNFS option enabled. If this happens, and you use the At Boot properties to resolve conflicts for the mount, the resolve conflict operation will fail. In such a case, use the Now properties instead.
