Failed to switch root: os-release file is missing #18

So I'm noticing this error today. I get thrown into a emergency shell and the below is some output with errors. It's saying something about os-release missing but it is there. /etc/os-release which is a symlink to /usr/lib/os-release exists.

● initrd-switch-root.service - Switch Root

And what my os-release file looks like below

Solved! I have my /boot files on a different partition, both rootfs and boot are on a Micro SD card. I changed the kernel I use for my device and that recently changed the device name from mmcblk0p1 to mmcblk1p1. The solution is to use the UUID of the partition instead of the dev name in the /etc/fstab.
