Booting to Emergency Mode after restoring snapshot using Timeshift.

Recently I set up Arch Linux on my laptop with BTRFS Subvolumes and Timeshift and it was working perfectly with Linux Zen Kernel. I messed up my home folder somehow so I decided to revert to a different snapshot. But the moment I restored the snapshot and rebooted, it loaded the kernel this showed up on screen:

I don't know what to do about it. I've tried checking /etc/fstab, tried booting to different kernel, tried restoring an older snapshot, tried btrfs check using live usb, "journalctl -xb" didn't provide much noticable error info. I even tried reinstalling linux and linux-zen and updating initramfs and updating grub. Still it's not booting.

How about sharing the log output - not much we can do without more information, either.
For future backup handling I would suggest backing up your $HOME using a different method than including it in your timeshift snapshots.

First thing, I'm guessing you have 'quiet' in the kernel command line? Get rid of that, it may show you what's actually failing.

Okay I'll give the logs here the next time I try to fix, maybe in 2-3 days.

Re: Booting to Emergency Mode after restoring snapshot using Timeshift.

For anyone wondering in the future (if it happens to you) know that you can input your root account password and:

 mount -o subvol=@home /dev/yourdevice /home

Where yourdevice can be a luks decrypted device or your partition of choice.
I'm assuming a standard timeshift layout with @ for your root and @home for your home.
The problem is that the @home subvolume id after a restore changes and you may have a different subvolume id in your /etc/fstab file.
