The volrmmount utility calls rmmount(1M) to, in effect, simulate an insertion
(-i) or an ejection (-e). Simulating an insertion often means that rmmount will mount the media. Conversely, simulating an ejection often means that rmmount will unmount the media. However, these actions can vary depending on the rmmount configuration and media type (see rmmount.conf(4)).
For example, if you use the default /etc/rmmount.conf and insert a music CD, it will not be mounted. However, you can configure rmmount so that it calls workman whenever a music CD is inserted.
This command allows you to override Volume Management's usual handling of media (see EXAMPLES below).
