Re: Single User Mode

Add "s" to your kernel boot parameter. (Same as sysvinit on every other distro.)

Re: Single User Mode

Add

systemd.unit=rescue.target

to the kernel command line. Parameters for sysvinit should also work b/c I think they are mapped to the appropriate systemd targets. But the underlying setting is not the "same as sysvinit" even though the same parameter may have the same effect due to the compatibility mappings.

Re: Single User Mode

Since a few moths ago, you can drop the ".target" from "systemd.unit=rescue.target".

https://wiki.archlinux.org/index.php/Kernel_parameters

It's easy to set it temporarily (by editing the boot menu when it shows up).

Don't forget to mark the topic as solved (by editing the first post) so that other people (including yourself sometimes) may find useful.

Re: Single User Mode

But .target won't hurt? Or is that syntax deprecated?

Re: Single User Mode

No, it's not deprecated. You can leave it in if you want, but it's easier to just remember it and type it on-the-fly when (or if?) you ever need to.

Re: Single User Mode

Oh, I like having the entry ready made so I don't have to remember *anything* if I'm panicking!

Re: Single User Mode

And how can I go into single-user mode from a running system?
systemctl rescue leaves user processes etc running.
