When we create gzip file from a payload, we use gzip module with option mtime
which is not available in python 2.6.
To be able to support it correctly, i've backported python 2.6.7 gzip

This should be removed with python 2.7 or 3.x

argparse is available in python2.7 (archlinux) and on python-argparse package in debian. So
we add a dependency to this package.

this already more easy unchrooting after failure by chrooting again,
solving issue and exiting (which remove mounts again)

chroot failed when root is missing dirs before resolv.conf fil

This is done to be able to use preparation from scripts

new option --preserve, -p is added

completion and is add -p <tab> doesnt work because cword is used and doesn't escape options from the list

gonnet-ifier...
