F2fs

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

Creating a F2FS partition

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

Create the partition:

# mkfs.f2fs /dev/sdxY

where /dev/sdxY is the volume that you wish to format in F2FS.

Mounting a F2FS partition

You may need to load the F2FS kernel module before mounting. Issue as root:

# modprobe f2fs

Then you can mount the partition:

# mount -t f2fs /dev/sdxY /mnt

Install Arch Linux on F2FS partition

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

1. Install f2fs-tools from official repositories while running arch from installation media.
2. Load f2fs kernel module as described.
3. Create root partition as F2FS as described.
4. Create /boot partition as ext4 (or any other supported filesystem).
5. Mount, install and chroot system as per official installation guide.
6. 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.
7. Don't forget to regenerate the initramfs image after that:

# mkinitcpio -p linux
