I noticed that the growpart script was missing from AWS image. This script is mentioned in all the docs on AWS for extending volumes. I think it would be a nice addition to the standard install Also the script needs to be patched to work with Funtoo's kernels. The ${mic} variable in the script expects a number and allot of our debian sources LTS kernels end in _p1 etc which is what the script looks at and fails. I removed it from the script and it worked, but it needs some better eyes than myself. Its around line 516 of the script. Thank you !
