how to run a shell in my systemd initramfs before pivot root

[marty leisner <maleisner@xxxxxxxxx>]

I'd like to be able to run a shell before completing the pivot (I'm running ubuntu core 20).

I'm well versed in systemV init, but not systemd.

How do I simulate the initramfs debugging methodology of "break=init" or "break=mount" using systemd (i.e. dropping into a

shell)?
