Chapter 9. System Configuration

9.28. dosfstools-4.2

9.28.1. Introduction to dosfstools

The dosfstools package contains various utilities for use with the FAT family of file systems.

Approximate build time: less than 0.1 SBU
Required disk space: 4.5 MB (with tests)

9.28.2. Kernel Configuration

Enable the following option in the kernel configuration and recompile the kernel if you need to mount a FAT-family filesystem: 

File systems --->
  DOS/FAT/EXFAT/NT Filesystems --->
    < /*/M> MSDOS fs support                                          [MSDOS_FS]
    <*/M>   VFAT (Windows-95) fs support                               [VFAT_FS]

Note that CONFIG_MSDOS_FS deliberately does not support long file names. CONFIG_VFAT_FS should be used instead unless you really want to enforce the DOS-style “8.3” file names.

You can mount a FAT-family filesystem once the kernel supports it. If you don't need to create, check, or relabel a FAT-family system, you may skip this package.

9.28.3. Installation of dosfstools

Prepare dosfstools by running the following commands: 

./configure --prefix=/usr            \
            --enable-compat-symlinks \
            --mandir=/usr/share/man  \
            --docdir=/usr/share/doc/dosfstools-4.2

Build libaio by running the following command: 

make

To test the results, issue: 

make check

Now, Install the package: 

make install
