Not directly. grub and init does not know about, or even care about, bash. |

You can change root's shell in /etc/passwd to sh and bash should run in sh |
| 12 |
mode. Or you can append init=/bin/sh to the grub boot line and try that. You |
| 13 |
will of course have to run all the init scripts yourself as init will not run |
| 14 |
when you do this. And you can't reboot either - when you exit the shell in |
| 15 |
this mode you'll get a panic |
