Is there a list of boot options we can use with grub? With 3.1 you could go through the menu's to see the different options but I can't see anything like that on 3.2. I'll put it up on the wiki if somebody can get me a list.
There are boot options, i don't remember exacty, but if you try scrolling through boot menu, additional field appears at the bottom and there you can see the boot line of the options you chose from menu, and you can edit them.
there are boot options. You just need to press f1 or f2 and it will begin showing you a list of options. the nohdparm option doesn't work though. Gentoo did some changes and Sabayon didn't catch them before the release so you have to use interactive mode to choose wether or not the hdparm service is started.
