Bug#827956: grub: Doesn't apply default entry from /etc/default/grub

Package: grub-pc
Version: 2.04-15
Followup-For: Bug #827956
I have a 'server' with no keyboard or monitor attached. I want to
boot into a 5.9 kernel instead of a 5.10 kernel to see whether there's a
NFS problem with 5.10.
But regardless what I specify as GRUB_DEFAULT in /etc/default/grub, it
always boots the top entry.
I've tried the following things:
- Use the value following "$menuentry_id_option"
- Placed single quotes around previous value
- Placed double quotes around previous value
- Replace "$menuentry_id_option" with "--id" in case it was incorrectly
not expanded/replaced in the grub entries
- Use a numerical value
None of which resulted in grub booting anything other then the top
entry.
If this can't be fixed, can then at least the documentation be updated
to say that grub only works interactively?
