TrueNAS Scale 22.02.4 recovery mode boot failing: Login Incorrect

[misosoup777]

Hello, I'm trying to boot into single user mode on Scale 22.02.4. In the grub menu, I'm choosing "Advanced>Recovery Mode". When the boot script runs, it dumps me to an endlessly looping "Login Incorrect" message that never stops and can't be interrupted. At no point am I asked to login, so it's not a bad username/password.

For additional context, I'm trying to get to SU mode to run a final zfs snap > zfs send > zfs receive from my old Tank to the new Tank before cutting over. I've already moved the boot-pool and system data to a mirrored pair of ssd's so now it's just application and nas data.

I realized that i never asked a question, so here's 3:
1) clearly recovery mode isn't supposed to do that, so any thoughts on why it is?
2) is there another way to get into single user mode?
3) am I over thinking this and just need to shutdown all the docker instances & services, do the final snap & send and be done with it?

thanks
