system has suddenly started not booting with systemd

the reboot command says

System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to system scope bus via local transport: Host is down

it has just started doing this as of yesterday

the only thing i think could have caused this is me building an lfs system

how do i make my computer boot with systemd again

Re: system has suddenly started not booting with systemd

You're "booting with system" and the $DBUS_SESSION_BUS_ADDRESS looks ok as well, but the communication w/ the session and system bus is broken.

cat /etc/hostname
ps aux #  you can "ps aux | nc termbin.com 9999" to upload that to termbin

I assume you cannot "sudo journalctl -b" either?

i can run journalctl, and the lock screen is fixed after a reboot (forgot to mention that systemd being screwed up also messed with the lock screen) so... i guess it's fixed

weird, that didn't happen on other reboots

Re: system has suddenly started not booting with systemd

You probably updated the system and the re-execution of systemd failed?

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
