And this is incredibly useful if you want to do something like
customising your install based on options passed the the kernel from
PXE Linux. You can parse your kernel options from /proc/cmdline and do
some very nice things:

[sam at samlap ~]$ cat /proc/cmdline
ro root=/dev/VolGroup00/LogVol00 rhgb quiet usbcore.autosuspend=1
