Kernel Upgrades Completed

     Kernel upgrades are finally completed.  It took abnormally wrong because something went wrong with the kernel install on mail and it ended up with a grub configuration pointing to two ancient kernels that no longer exist and thus it was unable to boot.

     I was able to fix the grub configuration with boot repair but then had to manually mount all the shell servers NFS partitions from it as it was dead when they booted.
