25 Notes:  This command only informs the system of your intention to
26 preload a particular volume on a specified device for a user.  It does
27 not check the loading of the proper volume on the device.  This label
28 checking is done at attach time.

30 Use of the preload command does not preserve the preloaded device.  The
31 preloaded volume may be automatically unloaded if another user of the
32 system requests a mount of a different volume on the preloaded device.
33 
34 The user name specified may contain fields that match any string.
35 These are specified by the use of an asterisk (*) in the appropriate
36 field.  For example, the user name "*.Proj.*" will match any user on
37 the project Proj.  Also, missing trailing fields are assumed to be *.
38 For example, "*.Proj" also matches any user in the Proj project.
