Is there a cross-distribution way to know the boot parameters supplied to the kernel?

Assuming you're asking about the options passed to the current-running kernel?
If the /proc filesystem is in use, /proc/cmdline tells you exactly what options were passed to the kernel.
$ cat /proc/cmdline root=UUID=3630dd43-f9f9-40b1-8a5f-72c13f2b309c ro quiet splashIf there's no /proc filesystem, you can get an idea by finding the current kernel's entry in grub.conf or other bootloader configuration. (Use "uname -r" to see what kernel is currently running.) This won't tell you what WAS used to boot the current kernel, just what is NORMALLY used.

Note for option 2: grub on Ubuntu uses /boot/grub/menu.lst for its configuration. I think other systems may use /etc/grub.conf. Commented Oct 1, 2009 at 22:17
I'm guessing you're talking about the Linux Kernel, so there is a set of standard parameters which it accepts.
