Each tarfile in this directory contains a kernel and associated
ramdisks suitable for upload to Eucalyptus that provides 
 * EBS-root like functionality
 * 'loader' functionality (ability to run a kernel inside the image as
   done on EC2 with pv-grub or on UEC of 10.10 with
   uec-publish-tarball --loader)

To use a loader tarfile with loader ramdisks and amis.
Note, that publishing kernels and ramdisks requires admin.  If you
do not have admin credentials, then your only option is to use an existing
kernel and create a loader-ami against the same kernel as described above.

 * download tarfile
 * extract tarfile
   tar -Sxvzf loader-*.tar.gz
 * publish kernel
   uec-publish-image --type kernel --verbose \
      amd64 ubuntu-kernels/*-kernel ubuntu-kernels
 * publish the ami loader
   # this is either as published above, or an existing kernel that matches
   # this version.
   AKI=eki-ABCDEFG
   uec-publish-image --kernel "${AKI}" --type image --verbose \
      amd64 loader-amis/*-sdb1.img loader-amis
 * publish instance-store loader ramdisk
   uec-publish-image --type ramdisk --verbose \
      amd64 loader-ramdisks/*-loader loader-ramdisks
 * publish EBS-root loader ramdisk with 'root=/dev/sdb1'
   uec-publish-image --type ramdisk --verbose \
      amd64 loader-ramdisks/*-loader-sdb1 loader-ramdisks
