Thank you for the hint, I’m looking into how to change the path and will ask if I get lost, which might happen.
The output for cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-6.14.0-37-generic root=/dev/mapper/ubuntu–vg-ubuntu–lv ro quiet splash
For sudo awk ‘$1~/linux/’ /boot/grub/grub.cfg it is
linux /vmlinuz-6.17.0-29-generic root=/dev/mapper/ubuntu--vg-ubuntu--lv ro quiet splash $vt_handoff
linux /vmlinuz-6.17.0-29-generic root=/dev/mapper/ubuntu--vg-ubuntu--lv ro quiet splash $vt_handoff
linux /vmlinuz-6.17.0-29-generic root=/dev/mapper/ubuntu--vg-ubuntu--lv ro recovery nomodeset dis_ucode_ldr
linux /vmlinuz-6.14.0-37-generic root=/dev/mapper/ubuntu--vg-ubuntu--lv ro quiet splash $vt_handoff
linux /vmlinuz-6.14.0-37-generic root=/dev/mapper/ubuntu--vg-ubuntu--lv ro recovery nomodeset dis_ucode_ldr
linux /memtest86+x64.efi
linux /memtest86+x64.efi console=ttyS0,115200
And for cat /etc/fstab it’s
# /etc/fstab: static file system information.

# Use 'blkid' to print the universally unique identifier for a

# that works even if disks are added and removed. See fstab(5).
