I am putting together a new server with 64GB of RAM and I would like to copy the whole Linux OS into a tmpfs from the disk and use the tmpfs as the OS (and I will use rsync to back up the tmpfs to disk every five minutes or so).

What are you hoping to achieve by doing this ? – Iain Feb 21 '12 at 10:20

You're better off using a traditional ramdisk, as shmfs/tmpfs are not very efficient filesystem-wise.

Also voted to close, as you're not asking a question.
