Good Morning list,
Does anyone know if there is a way to print out as much of the startup ordering of all systemd units including what happens in the initramfs before the pivot_root happens?
I just want to be able to grep the output for two units I am interested in to know that one is indeed starting before the other. I’ve looked at the systemd-analyze plot but this is a large svg file that is hard to parse. Systemctl list-dependencies comes close, but is missing the initramfs.
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.
