how to use USB hard disk as /(root)

[hatahata]

acording to martinayotte's kind advice . i can run root as hard disk drive .

1) rewrite
cat /boot/uEnv.txt
console=tty0 console=ttyS0,115200n8 no_console_suspend
kernel_filename=pine64/Image
initrd_filename=initrd.img
optargs=disp.screen0_output_mode=720p60
ethaddr=36:c9:e3:f1:b8:05
root=/dev/sda1


2)do next script  clone-to-HDD.bat

Code:

ntpd -s
date
echo '--------------------'
mkdir -p /ma1
umount /ma1
mount /dev/sda1 /ma1
df
echo '--------------------'
read X
echo $X
cd /ma1
mkdir -p bin            etc home lib                opt        root       sbin           srv            usr var

for x in /bin          /etc /home /lib               /opt      /root       /sbin         /srv          /usr /var
do
rsync -avHx --delete  $x/  /ma1$x/
done

for x in    boot  dev                  media   mnt       proc         run                      sys  tmp
do
rm -rf /ma1/$x
done

cd /ma1
mkdir -p     boot  dev                  media   mnt       proc         run                     sys  tmp

3) rewrite   /ma1/etc/fstab
# <file system> <dir> <type> <options> <dump> <pass>
/dev/mmcblk0p1 /boot vfat defaults 0 2
#/dev/mmcblk0p2 / ext4 defaults,noatime 0 1

/dev/sda1 / ext4 defaults,noatime 0 1

/dev/sda2 none   swap    sw              0       0


4)reboot

then
df

/dev/sda1      151641080 1943572 141971488   2% /

tmpfs             100384       0    100384   0% /run/user/1000
