Hello,
 
	Armbian 25.8.1 on Helios64 BookWorm with Linux 6.12.42-current-rockchip64.
 
	I have my system booting from SD with OMV7 installed and several docker containers running.
 
	Everything is OK. Now I want to boot from emmc.
 
	 
 
	Used armbian-install selecting option boot from emmc - system on emmc.
 
	Formatting and copying goes Ok, but when I reboot from emmc (extracting th SD card), OMV7 presents the web frontend, but can't log in.
 
	journalctl reports errors accessing the drives, and looking on /etc/fstab, there's only the / partition mounted.
 
	Inserting and mounting the SD card in /mnt/sdcard I can see that in /mnt/sdcard/etc/fstab there's a lot of drives ready to be mounted :
 
	 
 
eclapton@helios64:~$ cat /mnt/sdcard/etc/fstab

	So, I thought the actual fstab was going to be copied over, unless it has to be recreated each boot by OMV.
 
	Also, I tried to copy /srv/salt and /srv/pillar from the old system on the SD card  to the new one on the emmc, as instructed un Kobol's webpage, and it helps
 
	making openmediavault-issue start, but the webpage doesn't still work.
 
	 
 
	sudo systemctl status shows nginx is not able to start :

	I suspect there's somewhere I have to change /dev/mmcblk1p1 for /dev/mmcblk0p1... but where?
 
	What am I missing?
 
	Thanks for your help.
