This is installed onto a USB drive, and stops here while booting, never getting to a login prompt.

Re: dbus-broker failing on boot

stat /mnt/dev /mnt/run

You're supposed to mount devfs and runfs there, but still those should be root:root/755

Edit: to be clear: you *are* mounting devfs and runfs there and there're currently not files in /mnt/dev or /mnt/run ?

Re: dbus-broker failing on boot

Doesn't arch-chroot and the regular boot process mount them there?
Anyway, once I ran chmod 755 on them those first 3 lines are no longer there, and the output is

/mnt/dev and /mnt/run are not currently mounted.

Re: dbus-broker failing on boot

Ideally - does the system now boot after fixing the permissions?
Can you boot the multi-user.target or rescue.target (2nd link below)?
Do devfs and esp. runfs now mount or does dbus-broker still complain?

Re: dbus-broker failing on boot

Still does not boot after fixing perms.
I am able to boot to rescue.target, and in the shell I can see devfs and runfs are mounted. I am not able to reach multi-user.target, with the same errors.

Re: dbus-broker failing on boot

Not chroot, rescue.target - the chroot is pointless, you're getting the runfs from the install iso or a systemd fabricated one from the working system.
Edit: you can in doubt post a photo of the output.

Re: dbus-broker failing on boot

I think this may have been caused by doing the install on a system that was not the arch install disk, and having mount point be inside the home dir instead of /mnt.
