Edit the Boot Command Line with systemd

If you hit a boot error where there is a start job that cannot be terminated, you can enter the systemd debug shell.

To do this, at the systemd-boot menu, hit the e key and specify: systemd.debug-shell=1.

In the future you can do this in configuration.nix:

systemd.additionalUpstreamSystemUnits = [ "debug-shell.service" ];

Then you can enter the shell on TTY9 and debug the problem.

When I run sudo systemctl enable --now debug-shell, the following error appears

Failed to enable unit: File /etc/systemd/system/sysinit.target.wants/debug-shell.service: Read-only file system

Do you know how to solve it?
