Greetings, I've just finished installing a new system, choosing systemd-boot rather than grub. The handbook says that /etc/kernel/cmdline should contain 'quiet splash', but that's clearly not the whole story so I improvised.
'blkid | grep nvme0n1p5' shows this: /dev/nvme0n1p5: LABEL="RootFS" UUID="7ab169d9-03cb-44ce-98f6-1955c2458a4c" BLOCK_SIZE="4096" TYPE="ext4" PARTLABEL="root" PARTUUID="aeb1b1eb-7995-44ac-84ad-0e999ff4459d" ...so I put this into /etc/kernel/cmdline: root=UUID=7ab169d9-03cb-44ce-98f6-1955c2458a4c quiet splash Then on rebooting, I get 'Cannot open blockdev' or similar. Should there be some punctuation in my command line? Or perhaps I should have specified the PARTUUID instead of the device UUID. This is one of the few places where the handbook doesn't show an example. I can't check online at the moment because the site's down.
