Boot up error: Systemd

The system will hang on boot up with this error:


It occurred after a pacman -Syu

I tried reinstalling grub, tried editing fstab

This solution didn't fix it either.

nor did this

the uuid for 5f47b406.... is the root partition in /etc/fstab  ... and was changed to /dev/sda3 ... still did nothing. boot up still tries to search for the uuid. Any idea what I have missed?

Re: Boot up error: Systemd

I have tried several things

removing devpts / shm
removing UUID and using /dev/sda (like below)
Using labels instead of UUID
having a blank fstab with no info what so ever ( systemd still finds the root directory )

# /etc/fstab: static file system information

This is the output of lsblk -f
Note that I'm not able to even boot up, so this is the view of lsblk from the linux live boot from usb... ie after mounting /dev/sda3 and viewing contents of all files...

this is /etc/default/grub

#GRUB_INIT_TUNE="480 440 1"


Any idea where the boot up log files are? I have grub set to


...which has allowed me to see the error showing the uuid even though it's not set in fstab (above pic on first post)
If I set it to debug, I get spammed with info which I'm unable to figure out what or where the problem lays.

Re: Boot up error: Systemd

This is not the problem but you should (1) remove devpts and shm from fstab (2) alter lines in fstab ending in "0 1" to "0 2" with the sole exception of /. That is, /boot should be "0 2".

I'm afraid I can't figure out how to view your image - I get a thumbnail or a bunch of links to the thumbnail and file info. What does the error actually say?
