RightImage v3.0 (32-bit, 64-bit)

Release Date:  June 17, 2008
Nickname: RightImage CentOS5_0V3_0_0
IDs: ami-d8a347b1 (32-bit), ami-c8ac48a1 (64-bit)
Locations: rightscale_images/CentOS5_0V3_0_0.img (32-bit), rightscale_images/CentOS5_0V3_0_0.img (64-bit)

Use the 32-bit version for m1.small and c1.medium instances.  Use the 64-bit version for all other instance types.

• New Features
• Support  for new Amazon Kernel Modules including the Linux 2.6.18 kernel.
• The following packages were added/updated: lynx,pkgconfig,screen,rrdtool-1.2.27-2.  Some of these packages were previously unsupported. 
• rpc_pipefs, a new feature for NFS, was added to fstab.
• Improved logging - There will only be one audit entry per boot sequence.  The log file /var/log/install will contain all of the output from the boot process.  The audit entry showing the log on the web site is now updated during script execution.  The audit entry summary now displays the name of the currently executing script.  The execution time of each script, yum install, and attachment downloads are now logged.
• Decommission Scripts - When a server is being terminated, decommission scripts will be run as part of the shutdown sequence.  Since Amazon forces server termination after approximately 100 seconds, these scripts will need to complete execution during this time.  See Decommission Scripts.
   

• Changes and Bug Fixes
• In v2.0, the swap partition was missing on m1.small instances because it was not a part of the fstab.  The swap partition was added to fstab, which should prevent some out-of-memory situations.
• Upgraded RubyGems to V1.0.1
• In v2.0, a nosegneg bootup warning message would appear.  This problem was fixed and the warning message no longer appears at bootup.
• The yum configuration was changed to get the GSG key from the local disk that's initialized from the image.  This change helps prevent errors that were occurring when downloading the key.
• All yum repos were moved to redundant mirror servers and off of S3, which yields more reliable boots.
• Operational Scripts & Server Actions - The detection of success/failure was improved and audit entries for these actions will now have the appropriate "success:" or "failure:" summary.
• Additional Retries - A retry will now be performed after an attachment download failure. The software installation using yum will also be retried when a failure is detected.
• Working directory changed - Scripts are now executed out of an isolated directory in /tmp.
• Attachment Checksums - Attachments are now checked against the etag in order to detect stale attachments and update them before running scripts.
