Space is taken from the lower-priority systems first.
The device associated with path can be a device already known to the system, defined at system configuration time, or it can be a previously unspecified device. Otherwise, if a filesystem exists on the device, swap is added following the filesystem, or if no filesystem exists, the complete device is used for swap. See the appropriate system administrator's manual for information on how the size of the swap area is calculated. The min , limit , and reserve arguments are passed and used only if the path argument names a directory. A component of the path prefix denies search permission.
