-EROFS is still working in progress, thus it is not suitable
-for all productive uses. play at your own risk :)
-
-TODO List:
- - add the missing error handling code
- (mainly existed in xattr and decompression submodules);
-
- - finalize erofs ondisk format design (which means that
- minor on-disk revisions could happen later);
-
- - documentation and detailed technical analysis;
-
- - general code review and clean up
- (including confusing variable names and code snippets);
-
- - support larger compressed clustersizes for selection
- (currently erofs only works as expected with the page-sized
- compressed cluster configuration, usually 4KB);
-
- - support more lossless data compression algorithms
- in addition to LZ4 algorithms in VLE approach;
-
- - data deduplication and other useful features.
-
-The following git tree provides the file system user-space
-tools under development (ex, formatting tool mkfs.erofs):
->> git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs-utils.git
-
-The open-source development of erofs-utils is at the early stage.
-Contact the original author Li Guifu <bluce.liguifu@huawei.com> and
-the co-maintainer Fang Wei <fangwei1@huawei.com> for the latest news
-and more details.
-
-Code, suggestions, etc, are welcome. Please feel free to
-ask and send patches,
