Hello everybody,
Since I've updated my desktop on 17th July, I am not able to login via lightdm, it simply goes back to login screen. After failed login attempt, when I switch to tty and login I am greeted with a message that my home directory is missing. Indeed, it is.
user@arch $ ls /home
user@arch $Interestingly, when I do not try logging in with lightdm but switch to tty as soon as login screen is displayed, I can login without any problem. Logging in via SSH tty works fine as well. Apparently, failed login attempt with lightdm breaks something on my system so that any next login attempts are failed as well.
On my system, /home, /var, and /opt/hdd directories are bind filesystems located on a second drive.

It looks like they're not mounted before lightdm is started.
I've been using my Arch desktop for almost 4 years now and everything worked fine as far as my fstab is concerned. Has something changed recently? What should I correct on my system to be able to login with lightdm?

If you perform a full system update now does the issue still remain?
If so please post the journal from a boot with the issue.

I performed a full system update and the issue no longer occurs. Funny as lightdm was not actually upgraded. Maybe it was related to systemd? I've read somewhere that on systemd systems fstab is translated to systemd units.

Most likely fixed by an update to lvm2.
