What to do when systemd wont boot into shell?
After fixing /etc/fstab, run systemctl daemon-reload to let systemd refresh its view of it. If not even the emergency target works, you can boot directly into a shell with init=/bin/sh. This may be necessary in case systemd itself or some libraries it depends on are damaged by filesystem corruption.
What causes systemd to go into emergency mode?
It’s usually when a .mount unit for a local filesystem fails, causing local-fs.target to fail. Or when your initramfs fails to mount the root filesystem, if your initramfs uses systemd. local-fs.target has OnFailure=emergency.target.
How to boot directly into the emergency shell?

Note that in the emergency shell you will have to remount the root filesystem read-write by yourself before editing any files: Common issues that can be resolved in the emergency shell are bad lines in /etc/fstab.
How to enable systemd debug shell in command line?
systemd.debug-shell=1 on the kernel command line.

What to do if your machine gets stuck during boot?
If your machine gets stuck during boot, first check if the hang happens before or after control passes to systemd. Try to boot without rhgb and quiet on the kernel command line.
