[SOLVED] I don't have / anymore

This is great.

Basically on startup I'm fine until I get past loading udev...Then all the modules and daemons come up and they all fail, until Hardware Abstraction Layer, which hangs forever. All the errors I get say touch cannot change permission b/c file system is read-only.
The only clue I have is that on shutdown I got a notice in that / didn't exist in /etc/fstab or /etc/mtab. This was after I just blindly copied /etc/fstab.pacnew /etc/fstab without looking at it (Basically, pacman told me to. And the first one I looked at looked fine)

So, is there a way for me to edit /etc/fstab from GRUB? Or should I put in a LiveCD/Mount the hard drive to another computer?

Boot from a LiveCD (I recommend Recovery is Possible for all your recovery needs; Arch's install cd should do as well), mount Arch's root partition if needed and edit fstab.

Pacman has never once told me to copy a file over top of a new one, so I wouldn't go laying the blame on pacman   Anything with a .pacnew should always be compared to the current configuration file before being copied over. 

As the previous poster said, just boot from a LiveCD and mount the partition.  That's the easiest way to fix the problem.  Now in the future, diff is your friend

diff /etc/fstab /etc/fstab.pacnew

Thanks for the diff thing.

Awesome, this computer won't boot from CD. Label this Solved anyways, I'll take it from here.

Re: [SOLVED] I don't have / anymore

you could boot from a live usb image.  also you must label the thread solved yourself.
