Feature request: Support F2FS filesystem for root partition

[jimis]

I guess this is more appropriate project to report this feature request. Copying verbatim from raspberrypi/noobs#596 :

F2FS has been designed on the basis of log-structured filesystems, with the goal of performing optimally on managed flash media like SD cards, minimizing writes and extending their lifetime. It has seen some usage on Android phones, and it's constantly being improved with features that Raspberry Pi would very much like to have, like online compression.

Currently Raspberry Pi OS root partition can be converted to F2FS using a time-consuming process:

• Mount SD card with Linux PC
• Back up root partition
• Make F2FS filesystem on the SD card
• Restore backup to the new partition
• Update fstab and boot command line on the SD card

This is a dangerous and write-intensive process. In order to avoid it, it would be nice if installation could be done directly on a F2FS root partition.

Just waiting for some evidence that F2FS fixes more issues than it causes. At the very least, right now runs fsck on every single boot and I'm not sure that it can recover if it finds an issue, since it's running on a mounted partition. I suspect it will need initramfs to work properly.
