F2FS (Flash-Friendly File System) is a file system intended for NAND-based flash memory. It is supported from kernel 3.8 onwards.

In order to create a F2FS partition, install f2fs-tools from the official repositories.

Create the partition:

# mkfs.f2fs -l mylabel /dev/sdxY

where /dev/sdxY is the target volume to format in F2FS.

Users will likely need to manually load the F2FS kernel module before mounting. Issue as root:

# modprobe f2fs

The partition can then be mounted:

# mount -t f2fs /dev/sdxY /mnt

With the latest installation media (2013.04.01) it is possible to install system on F2FS partition:

Install f2fs-tools from official repositories while running arch from installation media.
Load f2fs kernel module as described.
Create root partition as F2FS as described.
Create /boot partition as ext4 (or any other supported filesystem).
Mount, install and chroot system as per official installation guide.
On installed system add f2fs to modules section in /etc/mkinitcpio.conf and remove fsck from hooks section since F2FS does not have fsck implementation yet.
Don't forget to regenerate the initramfs image after that:

# mkinitcpio -p linux
