Unlock a chroot during setup.
The locking technique (if any) may vary depending upon the chroot type and setup stage. For example, during creation of an LVM snapshot a block device might require locking, but afterwards this will change to the new block device.
An error will be thrown on failure.
type | the type of setup being performed |
lock | true to lock, false to unlock |
status | the exit status of the setup commands (0 for success, nonzero for failure). |
