Hello list, |
| 2 |
|
| 3 |
James's recent thread on grub2 with several kernels prompted me to have |
| 4 |
another play with grub2. |
| 5 |
|
| 6 |
I followed the grub2 migration guide[1] up to and including where it says "At |
| 7 |
this point you should reboot your machine and select GRUB2 Chainload." I did |
| 8 |
that and found I was offered only one kernel, and something about advanced |
| 9 |
options, which I couldn't make head nor tail of. That one kernel did boot ok, |
| 10 |
but when I rebooted again into grub legacy and booted the same kernel my |
| 11 |
volume groups had not started. One more reboot fixed that. |
| 12 |
|
| 13 |
Now, my question is how to have grub2 offer me a choice of kernels from all |
| 14 |
those that are present in /boot (a separate ext2 partition). Not only that, |
| 15 |
but pass different softlevel selectors to them. Here's my grub.conf to |
| 16 |
illustrate what I mean: |
| 17 |
|

I've been operating this way for years and maintained the kernel versions |
| 61 |
manually. That was not a lot of work, with the help of some elementary bash- |
| 62 |
ing and copy&pasting, and I don't want the flexibility of boot options thrown |
| 63 |
away by switching to a supposedly better grub. |
| 64 |
|
| 65 |
Any ideas anyone? |
