info command is used to get information about an image. It will replace list command

this command is and helper to chroot inside payload mounting /{proc,sys,dev,dev/pts} fs
inside the chroot and disable daemon restart

this also fix bad display of all changelog in verbose mode

we now have a changelog command, no needs to overload list output

we can now set a minimal installsystems version in your description
install will not be able to read those images

Add tarfile from python 2.7.2

This allow method add in Tarfile to have filter parameter.
This give us filter capa on file to include.
Should be removed when python 2.7 will be the minimum version

Because we roolback to python 2.6 requirment, we need to ship.

as a corolary, invalid option are no more loaded

This allow displaying to be done without coloration

is new have now an force option to overwrite existing images

This allow and easy double extracting without needs to delete it before

is new try to instanciate the new created object. But it doesn't pass validation...

tarfile module fail to extract tarball with utf8 filenames when destination is an unicode
string. We need to convert dest as utf-8 string to restore an expected behaviour

We need installsystems is functional on squeeze systems...

So we needs to embed:
- argparse 2.7.1 (not in python2.6)
- progressbar 2.3 (not in debian squeeze)

We can now use installsystems without paramiko

Add a changelog file inside isimage with a custom format which allow
image creator to quickly show update between images

Add a isversion field inside isimage which tell which version of installsystems was used to build image

Also fix some bug in PipeFile

This commit introduce remote repository and file accross ssh

currently db badly create if directory already exists before creation
