Additionally, being able to extract log files from the system would be helpful. Once dropped into an initramfs shell, you can type '''httpd'''. You should then be able to point a web browser to the IP address of the system and view the contents of /var/log .
There is another initramfs boot parameter which can purposely drop you into the initramfs shell during different stages of the initial boot sequence. The parameter is '''break=[option]''' where option can be: top, modules, premount, mount, bottom, or init. The default is premount if no options are specified. More information about the break= parameters can be found in "/usr/share/initramfs-tools/init" on your Ubuntu system.
