e2fsprogs: mke2fs: add the ability to copy files from a given directory
We will add a -d option which will be used for adding the files from a
given directory to the filesystem, it is similiar to genext2fs, but
genext2fs doesn't fully support ext4.
* We already have the basic operations in debugfs:
- Copy regular file
- Create directory
- Create symlink
- Create special file
We will move these operations into create_inode.h and create_inode.c,
then let both mke2fs and debugfs use them.
* What we need to do are:
- Copy the given directory recursively, this will be done by the
populate_fs()
- Set the owner, mode and other informations
- Handle the hard links
TODO:
- The libext2fs can't create the socket file (S_IFSOCK), do we have a
plan to support it ?
