i try nand-sata-install.sh .

 

namely

 

 

before nand-sata-install.sh

   usb hard disk ----orange pi PI -----micro sd

   (sda)

 

 

fdisk -l /dev/sda

after nand-sata-install.sh     plus     rewriting  swap line of /etc/fstab

namely root is over 200GB ( in HDD)

i think hard disk is more sutable for hevy duty so nand-sata-install.sh is good tool for us .

 

{ ls /boot/ } is
System.map-3.4.110-sun8i  bin  boot.bmp  boot.cmd  boot.scr  config-3.4.110-sun8i  script.bin  vmlinuz-3.4.110-sun8i  zImage

 

and

when gparted , /media/mmc apear .

 

and  {ls /media/mmc}  is
bin   dev  home  lost+found  media  opt   root  sbin     srv  tmp  var
boot  etc  lib   ma1         mnt    proc  run   selinux  sys  usr

 

can i erase /media/mmc folda except boot ?

( rm -rf /media/mmc/bin  and so on)

if i get  redundant sd card , i try experiment .

-------------

regards

i have done home work .

 

the present state is that /boot is in 32GB sd .

 

i intend to change 32GB sd for 4GB sd .

 

 

 

with kali linux , i insert 4GB sd to kali linux PC .

 

dd if=/Armbian_5.05_Orangepih3_Debian_jessie_3.4.110_desktop.raw  of=/dev/sdb bs=16M

 

 

and over internet , by sftp  i get /boot of  32GB sd ,

and cp -pR  {/boot/* of 32GB sd }  /mb1

and

cd /mb1

rm -rf  usr var .....and so on

 

 

so

the content of 4GB sd card is
 

ls -l /boot/
total 6964
-rw-r--r-- 1 root root 2107649  3月  9 04:03 System.map-3.4.110-sun8i

lrwxrwxrwx 1 root root      21  3月  9 04:23 zImage -> vmlinuz-3.4.110-sun8i

 

 

and i can boot armbian

 

now

250GB USB hard disk(this is /)-------[orange pi PC]---micro sd 4GB(this is  /boot)

i spare 32 GB sd card   and    as /   hard disk  is more tough than sd card , so i think .
