I have rebuilt all of the "generic"(did not have SL modifications)s rpm
for Update 6 for i386 and x86_64.

These rpms are available from

ftp://ftp.scientific.org/linux/scientific/30rolling/i386/errata/bugfix/RPMS/
ftp://ftp.scientific.org/linux/scientific/30rolling/x86_64/errata/bugfix/RPMS/

Both of these areas are yumable.

The only Update 6 rpms that are NOT included here are

 anaconda-9.1.6.8-2.RHEL.src.rpm  	Have to put in the SL changes
 redhat-artwork-0.73.3-2E.src.rpm	Have to put in the SL changes
 firstboot-1.1.33-1.src.rpm		Have to put in the SL changes
 redhat-release-3AS-13.6.2.src.rpm	This turns into sl-release

The Update 6 kernel was just released to the "errata" area as it is a 
security errata.

Please test these rpms and let us know if there are any issues with them.

Thanks
