Sorry about the HTML, didn't realise. |

If I press enter, I get a login prompt, and can login as root. |
4 |
Thats how I know the partitions are mounted but are readonly. |
5 |
I can't do shutdown or reboot nor write to any disk. |

|
7 |
I originally was getting a kernel panic with the boot partition as ext4. |
8 |
I reformated to ext2, reinstalled grub and recopied the kernel. |
9 |
There is no panic that I can see now. |

|
11 |
On my old system I needed an initramfs & the first few attempts left |
12 |
me in a similar state: partitions mounted, but all readonly. Fixed |
13 |
that by letting genkernel generate the initrd. |
14 |
|
15 |
As far as I can tell all the right stuff is in the right place, I'll |
16 |
reboot again and check that. I'm also not sure if home is mounted |
