I’m moving a Linux Mint 21.1 build I currently have on a external SSD disk to my NVMe, but for some reason initrd can’t find /sbin/init in the root partition when booting in the NVMe, although it can do it just fine on the SSD (and they’re copies of one another).
The only difference between the initrd in my SSD and in the NVMe is that I added the vmd and nvme modules needed for initrd to recognize my NVMe, which it does correctly (you can see it identifies and even mounts the root partition).
And obviously, I changed the UUIDs of the partitions accordingly in the bootloader and in /etc/fstab, so it is trying to mount the correct partition (nvme0n1p2) on /, that’s the correct partition and it contains /sbin/init.
/sbin/init is a symlink to /lib/systemd/systemd, which is there (/lib is a symlink to /usr/lib, all of them are there, nothing is missing).
I really can’t wrap my head around of what is going wrong, because it does mount the partition correctly.
Here’s a part of the initrd messages in my SSD (working) until the first message from systemd (which means systemd has been executed):
