On Centos 4.x 32 I want to create like a 64Mbyte ramdisk. Is there a problem putting 30k to 80k empty files on a ramdisk? Is there a simple howto on creating a ramdisk that anyone knows of off the top of there head?

mkdir /mnt/ram && mount -v -t tmpfs -o size=64M none /mnt/ram

If you want to use the RAM disk permanently you could use an entry in /etc/fstab: none /mnt/ram tmpfs size=64M 0 0

Besides, there is already a RAM disk available: /dev/shm
