Question about GRUB
| Cheraphy (815) |  |

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? edit: forgot to actually ask my question. Fixed it. What can I say, it's 4 a.m. :P | |

> a complete installation of Ubuntu on the SSD and load it all into ram on boot. ¿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. | |
