Details:

See line 135 of the attached grub config file -
"root=/dev/mapper/fedora_localhost--live-root" is repeated over and over. This
is causing a grub backtrace (can't remember what it said, I'll find it if it
turns out to be important), which goes away when the repeats are removed. I
suspect it has something to do with
'root=/dev/mapper/root=/dev/mapper/fedora_localhost--live-root' ending with
'root'.

This has happened twice after my package manager (dnf) updated the kernel.
When I re-run grub2-mkconfig, it produces the correct output, and I can't get
it to make the error on-demand. I would imagine this is the sort of logic bug
that becomes obvious when you re-read the code, but let me know if you need
any more info.

Grub version: 2.04
Fedora 33
Linux kernel 5.9.13 (although the config would have been generated on a
different kernel)
