I did an upgrade on my SRX and purposely left the old image on the disk - just in case. So now, things look like they are working okay and I was going to snapshot over the old image. Before I do, I have a couple of files that are on there that I need to copy of so I figured I could just reboot and interrupt the boot and tell it to boot from the backup partition but it keeps booting into the updated partition and not the old one.

Interrupting the boot and changing the boot.current didn't seem to help either:

So basically I want to boot to /dev/da0s1a.
Do I need to change the currdev to disk0s1? I've not seen any reference to changing this parameter and figured before I do and brick my device, I'd ask.
Thanks!!!
