TUTORIAL: How to mount synoboot in shell to modify grub.cfg

Recommended Posts

This is a repost of an archive I posted in 2015.


This method works for DSM 6.2 using Jun's loader 1.03b for me.



1) Enable SSH and ssh into your DiskStation

2) Become root ( sudo -i )

3) Make a mount point ( mkdir -p /tmp/mountMe )

4) cd into /dev ( cd /dev )

5) mount synoboot1 to your mount point ( mount -t vfat synoboot1 /tmp/mountMe )

6) Profit!

admin@DiskStation:~# sudo -i
root@DiskStation:~# mkdir -p /tmp/mountMe
root@DiskStation:~# cd /dev
root@DiskStation:/dev# mount -t vfat synoboot1 /tmp/mountMe
root@DiskStation:/dev# ls -l /tmp/mountMe
