说明
pumount is the counterpart to pmount for unmounting removable devices without root privileges. It is a wrapper around the standard umount that permits normal users to unmount removable devices without a matching /etc/fstab entry. It handles encrypted dm-crypt/LUKS volumes and ensures proper cleanup. It also supports unmounting devices that have been brutally removed.

- --luks-force
- Force LUKS close even if pmount did not open the device.
- -d, --debug
