[SOLVED] dropped into an emergency shell after reboot

Hina · 2023-07-24 06:02:20

Here is what I did before this happened.

1. edited my bash_profile to run startx on login https://wiki.archlinux.org/title/Xinit# … X_at_login
2. run pacman -Syu to update system (it has been a little over a week since last update)
3. run poweroff from the command line -> system freezes and nothing happens -> I turn off the system with the power button and restart
4. I am greeted with emergency shell as in the picture which is unresponsive

Further normal reboots result in the same screen, but using the grub fallback initramfs option I was able to boot into my system.

I feel a little out of my depth with this one but I hope to get to the bottom of this.

UPDATE: my system boots now normally after updating to systemd 254-1

I encountered the same thing today after updating. In my case the UUID of the device it couldn't mount corresponds to the root filesystem. (i.e. mounted to /)

This appears to be related to the systemd 253.7 update. I was able to restore my system be running the command "sudo pacman -U /var/cache/pacman/pkg/systemd*253.6-2*.pkg.tar.zst" though obviously this isn't a long-term solution.

Are either of you using an encrypted root partition?

I submitted an Arch bug here: https://bugs.archlinux.org/task/79187

When looking upstream, systemd has this commit immediately after the 253.7 release: https://github.com/systemd/systemd-stab … 5926ee0d14
This fixes issues with non-btrfs disks, where my various partitions are ext4. After building systemd 253.7 locally with this commit applied, I am able to boot as normal.

Yeah, no - check the bug akb825 submitted (and that I found pretty much after hitting submit
