Public bug reported:
Warning: os-prober will not be executed to detect other bootable partitions.
----
Lubuntu noble install to
- hp dc7700 (c2d-e6320, 8gb, amd/ati rv610/radeon hd2400 pro/xt)
System had two Lubuntu noble installs on box; original full disk install (sda1)
+ install alongside (sda2)
This box is legacy (BIOS) or pre-uEFI (2005 HP Compaq) so no ESP was created at
install time
guiverc@dc7700-3:~$ blkid

BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="b22c54df-01"
** expected result
On reboot post-install (Lubuntu so calamares install) I grub did NOT
appear, so I could boot into the untouched install & checked it worked
(grub offered me two options correctly prior to install).
** actual result
No grub menu appeared, so no dual boot option was offered??
No problem, I'll just `update-grub` and that should fix it won't it?

The issue is
Warning: os-prober will not be executed to detect other bootable partitions.
Prior releases of Ubuntu haven't done this (new grub 2.06 change) with a
patch (ubuntu-os-prober-auto.patch) carried by Ubuntu that reverses this
upstream change..
If this is new behavior (for noble) we (Lubuntu at least) just need to
document it, as its a change to mantic, lunar & prior releases (inc.
kinetic, jammy which were 2.06 or later, it was default prior to jammy
anyway).
Maybe I'm missing something... I'll correct/add more as I can
