Support for checkpoint/restore of a file system type often needs to be explicitly implemented, as each file system may have a unique set of features and just mounting anything would be wrong. However, some file systems do not require special processing. A list of comma-separated, currently unsupported, file system names that would "just work" can be specified with the
--enable-fs option (e.g.
--enable-fs hugetlbfs). In addition, the value
all can be used to will match any unsupported file system.
|Note: When this option is used, restore may fail if the specified file system requires any special restore logic.|
