 Posted: Fri Jan 10, 2003 4:11 pm Post subject: Can GRUB run in failsafe? |
 |
|
Somtimes you do something that you really regret afterwards!
Like I run a seventeenorbust.com (a distributed attempt at solving the Sierpinsi problem) client, and wanted it to start automatically at startup...
Therefore I added a line in /etc/local.start, which made the client run!
And upon startup, the client ran! - It ran and it ran, and there was nothing I could do about it. CTRL+F? just gave me blank screens without any login forms... and CTRL+C didn't do anything. Therefore I can't even edit /etc/local.start to remove the line that I added!  .
I use GRUB; is there any way to make it pass running local.start? - Is there some key combination that ends the startup process, and gives me a terminal (CTRL+ALT+DELETE won't do)... And yes, i have tried pressing CTRL+ALT, and lying my other arm on the keyboard. |

Reboot. At the GRUB prompt, edit the command line such that you append the following:
Continue with this new boot command and the system should drop you into a BASH shell, without going through rc.
Of course, very little will be setup here, so you may need to define a few PATHs and manually load any modules such as networking in addition to mounting any filesystems manually (depends on how you've set things up).

Still no good... GRUB dsoesn't know anything about a init command.
And I just wondered... before GRUB want's to do anything, it loads the kernel, and with the kernel, it loads local.start. Doesn't it? How shall I then skip it, if it is in the kernel automatically?
Shall I get one of my friends kernels on a disk and load that one instead? - That seems quite an awful lot just to pass a file! |

uhh... fixed it. I just added at the end of | Code: | | kernel /boot/bzImage root = /dev/hda3 |
, which gave me a bash shell. |

You need to add it to the end of the boot command, but anyway you've done it another way now.
