  2. Florian Diesch is correct. You can find information on this on the man page for proc.

    /proc/cmdline

    Arguments passed to the Linux kernel at boot time. Often done via a boot manager such as lilo(8) or grub(8).

    From my 14.04 terminal, I can cat my /proc/cmdline to see the parameters that my kernel was booted with:

    $ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-3.13.0-29-generic root=UUID=cabb338a-445e-4ed7-8f37-a78ddf5174b6 ro find_preseed=/preseed.cfg auto noprompt priority=critical locale=en_US quiet
