You don't waste any space by using tmpfs. Contrary to a ramdisk, space can be allocated dynamically, there is no underlying block device (just like initramfs compared to initrd). Infrequently accessed data will be swapped out. Jürgen _______________________________________________ arch mailing list [email protected] http://www.archlinux.org/mailman/listinfo/arch
