Introduction to dosfstools

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

This package is known to build and work properly using an LFS 12.1 platform.

Package Information

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 unsupport 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.

Install dosfstools by running the following commands:

./configure --prefix=/usr            \
