This page will detail how to have /tmp and /var/tmp run under a mounted RAMDISK /dev/ram0. This is done for several reasons. First, if /tmp and /var/tmp are mounted under root /, they can cause large amounts of disk fragmentation due to the creation/deletion of a large amount of files. Second there is a noticeable performance gain, especially when dealing with large programs, (ie, KDE, gnome, OpenOffice, Etc) that use /tmp and /var/tmp to store/interact with information. I would not recommend this process for systems with a small amounts of ram. | This page will detail how to have /tmp and /var/tmp run under a mounted RAMDISK /dev/ram0.

This page will detail how to have /tmp and /var/tmp run under a mounted RAMDISK /dev/ram0. This is done for several reasons. First, if /tmp and /var/tmp are mounted under root /, they can cause large amounts of disk fragmentation due to the creation/deletion of a large amount of files. Second there is a noticeable performance gain, especially when dealing with large programs, (ie, KDE, gnome, OpenOffice, Etc) that use /tmp and /var/tmp to store/interact with information. I would not recommend this process for systems with a small amounts of ram.
Contents
Ensure kernel has Ramdisk Support
--- Block devices
<*> RAM block device support
(16) Default number of RAM disks
(4096) Default RAM disk size (kbytes)
Tell the kernel to make the Ramdisk at boot
You will need to edit which ever boot loader menu you have {IE:grub, lilo} and add ramdisk_size=56000 to the kernel boot parameters. It should resemble the following. This tells the kernel to create a ramdisk 56Mb in size.
title CLFS YOUR_VERSION
root (hdX,X)
kernel /boot/clfs_YOUR_KENREL root=/dev/{XXX} ramdisk_size=56000
Add the process to the bootscripts
cd /etc/etc/rc.d/init.d/ patch -Np1 -i ~/mountfs-0.1-RAMDISKTMP-1.patch
Now you just need to reboot and sit back. Enjoy!
What is added to you boot scripts /etc/rc.d/init.d/mountfs
Adds a Boot Mesg to the screen during the boot process.
boot_mesg "Creating, Formating and Mounting Ramdisk tmp..."
Formats the ramdisk, We use ext2 because a journal is not needed.
mkfs.ext2 -q -m 0 /dev/ram0
We mount the newly formated ramdisk /dev/ram0 as /tmp
mount /dev/ram0 /tmp
We correct the permissions of /tmp to the correct ones.
chmod 1777 /tmp
We use a simple symlink to a add /var/tmp to the same mount
ln -sf /tmp /var/tmp
Print to the boot screen, [OK] when completed without error.
