erofs-utils
|
|
===========
|
|
erofs-utils includes user-space tools for erofs filesystem images.
|
|
Currently only mkfs.erofs is available.
|
|
|
|
Mkfs.erofs
|
|
----------
|
|
It can create 2 primary kinds of erofs images: (un)compressed.
|
|
- For compressed images, it's able to use several compression algorithms, but lz4(hc) are only supported due to the current linux kernel implementation.
|
|
- For uncompressed images, it can decide whether the last page of a file should be inlined or not properly [1].
|
|
How to generate erofs images
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
Currently lz4 and lz4hc are available for compression, e.g.
|
|
$ mkfs.erofs -zlz4hc foo.erofs.img foo/
|
|
Or leave all files uncompressed as a option:
|
|
$ mkfs.erofs foo.erofs.img foo/
|
|
|
|
Known issues
|
|
~~~~~~~~~~~~
|
|
1. LZ4HC cannot compress long zeroed buffer properly with
|
|
LZ4_compress_HC_destSize()
