Boot issues with the fstab

I am trying to install arch with btrfs subvolumes and I am trying to boot into the system with this command:

systemd-nspawn -bD /mnt

However, when it boots I cannot log in with root. I think I should be able to log in with no password.

I am also getting this error on boot:

[FAILED] Failed to start Remount Root and Kernel File Systems.
See 'systemctl status systemd-remount-fs.service' for details.

After looking into it, it I think that this is directly related to my settings on my fstab for my root partition, but any help would be appreciated. Here is my fstab:

# /dev/mapper/system UUID=59d69f6b-8370-44d9-908b-c57be7739b1f

Re: Boot issues with the fstab

Good morning.

However, when it boots I cannot log in with root. I think I should be able to log in with no password.

While in chroot, during the installation process did you set a password for root? What boot loader are you using?
If you did, then you should be able to log-in like so:
user: root
password: ******

[FAILED] Failed to start Remount Root and Kernel File Systems.
See 'systemctl status systemd-remount-fs.service' for details.

Post more info related to that command.

After looking into it, it I think that this is directly related to my settings on my fstab for my root partition, but any help would be appreciated. Here is my fstab:

Think about fstab as the guide that your system will use to mount your HDDS and/or SSDS every time it boots up. Just by looking at it I can see some things that are a little off, such as: the <fsck> should always be 1 when it comes to the root device (more info).

I'll post mine so you can have a better idea. keep in mind that I use ext4, I don't recognize the storage format chosen by you.

$ cat /etc/fstab 
# Static information about the filesystems.
# See fstab(5) for details.

Hope it helps.
