Title says it all. I changed my btrfs subvol names so I could use timeshift to manage my snapshots, after regenerating the initramfs and editing grub to point to the new subvol names all was fine however after I got a kernel upgrade recently, the latest grub entry for the kernel specifies the old subvol name, resulting in a failed boot. I dont know grub well enough to know what options to add to /etc/default/grub, or even if thats where I need to add it. After editing the entry manually it boots perfectly fine so theres my question. Is there a grub config option to specify the name for a subvolume to boot? I'd rather not manually edit grub.cfg every time theres a kernel update lol.
