in order to make it more generic grab information form lsb-release

# Build /etc/issue
KERNEL=`uname -sr`
. /etc/lsb-release
IP=`ifconfig eth0 | grep ‘inet addr:’ | cut -d: -f2 | awk ‘{ print $1}’`
echo “$DISTRIB_DESCRIPTION :: $KERNEL :: $IP” > /etc/issue
echo >> /etc/issue

i usually do the following for linux vm’s:

- set noatime in /etc/fstab for disks

- increase read-ahead:
blockdev –setra 4096 /dev/{sda,sda1,sda2,sdb,sdb1}

- change scheduler for disk
echo deadline > /sys/block/sda/queue/scheduler
echo deadline > /sys/block/sdb/queue/scheduler

- decrease need for swapping when enough memory is installed
sysctl -w vm.swappiness=0

This is one of the little things I like to do, a useful reminder of being root (and it looks pretty )
