You can use libext2fs to add some files and directories. But these interfaces might be changed because it isn't exported as an ABI. After it is released within a new e2fsprogs version, they will never be changed. > > Will "mount" from a linux with kernel 3.8 work with a partition > generated with this new e2fsprogs? Yes, you can mount a file system with inline data in a 3.8 kernel using this branch. Regards, - Zheng
