| 4 | Subject: [PATCH 01/11] mke2fs: add the ability to copy files from a given |
| 5 | directory |
| 6 | |
| 7 | We will add a -d option which will be used for adding the files from a |
| 8 | given directory to the filesystem, it is similiar to genext2fs, but |
| 9 | genext2fs doesn't fully support ext4. |
| 10 | |
| 11 | * We already have the basic operations in debugfs: |
| 12 | - Copy regular file |
| 13 | - Create directory |
| 14 | - Create symlink |
| 15 | - Create special file |
| 16 | |
| 17 | We will move these operations into create_inode.h and create_inode.c, |
| 18 | then let both mke2fs and debugfs use them. |
| 19 | |
| 20 | * What we need to do are: |
| 21 | - Copy the given directory recursively, this will be done by the |
| 22 | populate_fs() |
| 23 | - Set the owner, mode and other informations |
| 24 | - Handle the hard links |
| 25 | |
| 26 | TODO: |
| 27 | - The libext2fs can't create the socket file (S_IFSOCK), do we have a |
| 28 | plan to support it ? |
