mkcp - make a NILFS2 checkpoint

mkcp [options] [device]

mkcp is a utility for making a checkpoint or snapshot for the NILFS2 file system found in device. When device is omitted, it tries to find a NILFS2 file system from /proc/mounts.

This command is valid only for mounted NILFS2 file systems, and will fail if the device has no active mounts.

Create a snapshot.
Print the checkpoint number when successfully created.
Display help message and exit.
