In some comments about the multiple-distro setups there were rather |
| 17 |
vague references to occasional syntax problems between different |
| 18 |
distro's versions of grub. I don't know if it was due a change that |
| 19 |
was introduced upstream when grub was updated or some sort of RedHat |
| 20 |
custom-feature-backporting-bastardization. |
