Initramfs and rootfs are two fully independent systemd environments, no
matter which tool you use to inspect them. You can use `systemctl
list-dependencies` from within the initramfs as well, if you boot with the
"rd.break" kernel option which will provide an interactive shell in the
initramfs environment before pivot happens.

Note that `systemd-analyze plot` accepts --from-pattern and --to-pattern to
limit the units that will be shown.
