F2FS/en

F2FS (Flash-Friendly File System) is Article description::a designed for NAND flash-based devices. It is available in Linux  3.8.x and higher. This filesystem is a good choice when installing Gentoo on an eMMC,, , or a flash-based USB device.

Kernel
When enabling support to the filesystem in the Linux kernel, it is wise to enable at least "F2FS extended attributes" ( F2FS_FS_XATTR ) with "F2FS Access Control Lists" ( CONFIG_F2FS_FS_POSIX_ACL ) and "F2FS Security Labels" ( CONFIG_F2FS_FS_SECURITY ) suboptions.

"F2FS consistency checking feature" ( CONFIG_F2FS_CHECK_FS ) option in the list will enable F2FS's filesystem consistency checking. The checking will occur during run time and will decrease the filesystem's performance. This option provides an advantage when consistency is more important than speed.

Emerge
Install the userspace tools for the F2FS filesystem:

Creation
After emerging the userspace tools, create a filesystem by running the command followed by the appropriate device and partition number:
