update-initramfs would likely fail in this environment even if you had the binary, as it assumes the real root to be mounted. I'm not even sure you have your real /etc under /etc at this point.
Can't you just eliminate the problem that prevents real root from being mounted — import the array/pools manually and then ^D it so it can carry on its usual routine? 🤔
