# insert micro sd into other computer
# check for locations
# remount for consistent naming
sudo umount /dev/mmcblk0p1
sudo umount /dev/mmcblk0p2
sudo mkdir /media/boot
sudo mkdir /media/root
sudo mount -t vfat /dev/mmcblk0p1 /media/boot
sudo mount -t ext4 /dev/mmcblk0p2 /media/root
# make backup
sudo cp -a /media/root /home/user/backup-root
# create f2fs file system
sudo umount /dev/mmcblk0p2
sudo mkfs.f2fs /dev/mmcblk0p2
# restore root
sudo mount -t f2fs /dev/mmcblk0p2 /media/root
sudo cp -a /home/user/backup-root/* /media/root
# Modify boot files
## /dev/mmcblk0p2  /      f2fs    defaults,noatime,discard  0       1
