This enhances security and prevents accidental denial of service or exploit of SUID programs. Creating multiple partition offer you the following advantages: · Protection against denial of service attack. · Protection against SUID programs. · Faster booting. · Easy backup and upgrade management. · Ability for better control of mounted file system. · Limit each file system’s ability to grow. Warning: If previous file system or operating system exist on the hard drive and computer where you want to install your Linux system, we highly recommend, that you make a backup of your current system before proceeding with the disk partitioning. Step 1 For performance, stability and security reasons you must create something like the following partitions listed bellow on your computer. We suppose for this partition configuration the fact that you have a SCSI hard drive of 3.2 G. Of course you will need to adjust partition sizes according to your own needs and disk size. Partitions that must be created on your system: /boot   5MB   Kernel images are kept here. /usr    1000MB      Must be large, since all linux binaries programs are installed there. /home 500MB Proportional to the number of users you are intended to host. (e.i. 10MB per users * by the number of users 50 = 500MB). /chroot 400MB If you want to install programs in chroot jail environement. (e.i. DNS). /cache 400MB This is the cache partition of a proxy server. (e.i. Squid). /var     200MB Contains files that change when the system run normally. (e.i. log files). <Swap> 150MB Our swap partition. The virtual memory. /tmp   100MB Our temporary files partition. / 315MB Our root partition.
