| Subject: [PATCH 01/11] 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 ? |
| |
