CentOS 5.5 Kernel Upgrade and iotop Install

To run you need a kernel greater than what CentOS provides. The following steps guide this upgrade, so that you can use iotop.

cd /usr/src
tar xjf linux-
ln -s linux- linux
cd linux
make mrproper
cp /boot/config-`uname -r` .config
yes "" | make oldconfig (this updates .config to all defaults)

edit .config, adding or updating the following options:

make modules_install
make install

rpm -Uvh
tar zxvf iotop-0.4.3.tar.gz
cd iotop-0.4.3

Disclaimer: Perform the above instructions at your own risk.

For instructions on how to make the rpm (so the lengthy compilation can be done once for future installs), see
Note: will need to install rpm-build and ncurses-devel
