64 \fBlofiadm\fR administers \fBlofi\fR, the loopback file driver. \fBlofi\fR
65 allows a file to be associated with a block device. That file can then be
66 accessed through the block device. This is useful when the file contains an
67 image of some filesystem (such as a floppy or \fBCD-ROM\fR image), because the
68 block device can then be used with the normal system utilities for mounting,
69 checking or repairing filesystems. See \fBfsck\fR(1M) and \fBmount\fR(1M).

72 Use \fBlofiadm\fR to add a file as a loopback device, remove such an
73 association, or print information about the current associations.
