[bug #59717] Grub failing with backtrace due to error in automatically generated config file

[Joe Pater]

Follow-up Comment #1, bug #59717 (project grub):


[comment #0 original submission:]
> 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'.

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.
