umount.udisks2 - unmount file systems that have been mounted by UDisks2
program is a helper for the umount(8)
Its purpose is to clean up automatically created directories created at file
system mount-time. It should never be called directly.
This man page was originally written for UDisks2 by David Zeuthen
<firstname.lastname@example.org> with a lot of help from many others.
