I hope this is the correct section for this question.
In my opinion, one of the best kept secrets (or little used awesome features) of PCLinuxOS is the "Copy To Ram" feature used in the initial boot menu found on all the Live cd's. Is there a way to utilize this through a script with a hard drive installation?
I have to tell you, this feature sets the standard when it comes to speed! AWESOME!
If you have a lot of ram like me, you'll be amazed.
Anyway, any input on this matter would me much appreciated and I guarantee the community would go "bonkers" if it can be done.
I would suspect that the problem (one of many, I'm sure) of implementing this on a HDD install would be dataset size.
A) It is unknown (if the user installs more applications, etc)
B) It is (most likely) growing (see reason for point (A))
This would (eventually) create a scenario where
A) It would take longer and longer to boot, as time went on, as the installed dataset gets larger, until
B) It would no longer fit into RAM.
The reason this works so well in the Live CD scenario is because the dataset size is constant (and, under 1 GB, so it can easily fit in many current PC's RAM), and compressed as well (further reducing the size, and giving potential performance gains as compared to running from such slow media as optical drive).
I don't believe this is a good, general purpose goal.
If, however, you want to create a custom install (knowingly keeping it under a set size), then you would need to look into setting up a RAM disk, copying the system over to it, and getting the root
) directory mounted from there...
