That is not my understanding. From [1], "10_linux identifies kernels on |
| 18 |
the root device for the operating system in use and creates menu entries |
| 19 |
for these items." I take this to mean 10_linux is the script |
| 20 |
responsible for identifying the currently booted system (i.e., the "root |
| 21 |
device." |
| 22 |
|
| 23 |
Also from [1], with emphasis added "30_os-prober this script uses |
| 24 |
**os-prober to search for Linux** and other operating systems and places |
| 25 |
the results in the GRUB 2 menu. |
| 26 |
|
| 27 |
A review of the scripts 10_linux and 30_os-prober supplied by Gentoo |
| 28 |
with the grub and os-prober packages seems to confirm the Ubuntu |
| 29 |
documentation's accuracy. |
| 30 |
|
| 31 |
Regardless of which script is responsible, the problem remains that |
| 32 |
running 'grub-mkconfig -o /boot/grub/grub.cfg' under the circumstances |
| 33 |
outlined in my original post should find the other Linux operating |
| 34 |
systems, but doesn't. |
