| + | This is the one specified with the <code>-D|--images-dir $path</code> option. If not given CRIU uses current working directory. This is where all [[images]] are put. |
| + | |
| + | == Prev images directory == |
| + | |
| + | When using the [[memory changes tracking]] facility it's important to tell CRIU where images from previous run are. This is done by specifying the path with the <code>--prev-images-dir</code> option. |
| + | |
| + | Remember, that the path given should be ''relative to the images directory'', e.g. like this |
| + | |
| + | <pre> |
| + | # criu dump --images-dir ./images-1 --track-mem |
| + | # criu dump --images-dir ./images-2/ --prev-images-dir ../images-1 --track-mem |
| + | </pre> |
| + | |
| + | Symlinks in paths of absolute paths will not work as well unfortunately. |
| + | |
| + | == Working dir == |
| + | |
| + | All other files, e.g. [[logging|logs]], [[irmap]] cache, sockets for [[lazy migration|lazy server]] and other go to working dir. By default the working directory is the images directory, but it's possible to override one with the <code>-W|--work-dir $path</code> option. |
