Installing permanently to remove usb (18 replies)

Hi all,

what would be the steps to get the system installed in the "real" boot partition. E.g. for my NSA310 I want the system to be independent of the usb flash drive and instead have it boot from internal flash/HDD. With my limited understanding, given my partitions:

lsblk 
NAME      MAJ:MIN RM  SIZE RO TYPE   MOUNTPOINT
sda         8:0    0  1.8T  0 disk   
|-sda1      8:1    0  502M  0 part   
`-sda2      8:2    0  1.8T  0 part   
  `-md0     9:0    0  1.8T  0 linear 
sdb         8:16   1  7.6G  0 disk   
`-sdb1      8:17   1  7.6G  0 part   /
mtdblock0  31:0    0    1M  0 disk   
mtdblock1  31:1    0  512K  0 disk   
mtdblock2  31:2    0  512K  0 disk   
mtdblock3  31:3    0  512K  0 disk   
mtdblock4  31:4    0   10M  0 disk   
mtdblock5  31:5    0   10M  0 disk   
mtdblock6  31:6    0 47.8M  0 disk   
mtdblock7  31:7    0   10M  0 disk   
mtdblock8  31:8    0 47.8M  0 disk

I am assuming sda1 was created by NSA310 since it contains

l -h tmp/
total 479M
drwxr-xr-x 3 root root 1.0K Mar 13  2016 .
drwxr-xr-x 3 root root 4.0K Oct 15 00:13 ..
drwxr-xr-x 2 root root  12K Mar 13  2016 lost+found
-rwxrwxrwx 1 root root 341M Mar 13  2016 swap_ul6545p
-rw-r--r-- 1 root root 136M Mar 13  2016 sysdisk.img

which would make for sysdisk.img being the stock OS. I cannot mount the mtdblockX partitions so I would venture to guess I could overwrite the stuff in /dev/sda1 and modify uboot to load my kernel from there.
But how???

Thanks!
