The Debian project  announced the 6-th update of its stable distribution Debian 6.0 (codename squeeze). This update mainly adds corrections for security problems to the stable release, along with a few adjustments for serious problems. Security advisories were already published separately and are referenced where available.

Please note that this update does not constitute a new version of Debian 6.0 but only updates some of the packages included. There is no need to throw away 6.0 CDs or DVDs but only to update via an up-to-date Debian mirror after an installation, to cause any out of date packages to be updated.

Those who frequently install updates from won’t have to update many packages and most updates from are included in this update.

New installation media and CD and DVD images containing updated packages will be available soon at the regular locations.

Upgrading to this revision online is usually done by pointing the aptitude (or apt) package tool (see the sources.list(5) manual page) to one of Debian’s many FTP or HTTP mirrors. A comprehensive list of mirrors is available at:

Many sysadmins think about performance tunning as optimizing loops, memory use, algorithms, etc.But you don’t get a massive performance gains from optimizing CPU and memory use, but from eliminating I/O calls.

CPU, bandwidth, and memory strangulation is turning into additional and additional common on shared servers and virtualization systems, but practical disk throttling isn’t even on the horizon from what I can tell. Improper I/O usage from any app affects everybody.

Step1. Edit /etc/fstab file and add noatime for your root file system:

vim /etc/fstab

And then add noatime after errors=remount-ro

cat /etc/fstab
# /etc/fstab: static file system information.
# Use ‘blkid’ to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
