Question about GRUB
Through circumstance, a friend acquired a server mother board with 64Gigs of ram installed with room (and compatibility) to double it. As well, he has a SSD or two at his disposal. Basically the plan is to store a snapshot of a complete installation of Ubuntu on the SSD and load it all into ram on boot. I've never done any serious configuration of Grub before, so I wasn't sure if doing something like this with it would even be a possibility. But if it is, do guys have any thoughts on how I might go about doing this?

¿like a live CD?

I use a script that starts together with X, which reads all the files that are needed during a normal session.
They reside in the page cache after that.
Although I found that this provides little benefit with an SSD. Whether the files are read from the SSD or the page cache has become nearly irrelevant.

A Live CD generally does not load its entire contents into RAM at boot. It works the same way as when booting from a normal hard disk/SSD (data is read from the disc when it is first accessed).
Some Linux live CDs load everything into memory at boot... Damn Small Linux, for example.
