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 ?

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 ?
