Subject: [RFC 00/10] e2fsprogs/mke2fs: add an option: -d root-directory

This option is used for adding the files from the root-directory to the
filesystem, it is similiar to genext2fs, but genext2fs doesn't fully
support ext4.

* Questions
  - Is such an option acceptable ?

  - Most of the code have been in debugfs/debugfs.c already, I moved them to
    misc/util.c and modified them to let both mke2fs and debugfs can use them,
    maybe we should put these code in another separate file ?

  - Where can I get the up-to-date development git repo, please? I think that
    there would be conflicts with the dev git repo, I'd like to rebase it if I
    can get the repo, currently, I'm using this one:

    http://git.kernel.org/cgit/fs/ext2/e2fsprogs.git

* The size impact on misc/mke2fs:
   1,677,297 -> 1,728,110 (non stripped, about 50K increases)
   316,968 -> 325,160 (stripped, 8K increases)

Please feel free to give your comments.
