Use tar.xz for portage download if xzdec is present

This speeds up download (smaller file size)

Also requested in #43 for custom stage3 tarball specification.

Ideal script can be split into program logic as:

1. Processing of Interactive/command line parameters
2. Generates the lxc.conf file (from error checked parameters)
3. (future version) partition management (something like lvm with snapshot features?)
4. source image (tarball) management

I don't see any technical difficulties for other compression format, if current script updates to a more modular friendly way.

The truth is it is harder to do things right for bash.

The script structure is a remnant of the other lxc-distro scripts at the moment. I agree it's not really logical as a standalone thing.

As for partitioning, I think this is too low level for this script.

I don't have time to widen the scope that far (or to LV management). But I agree, it's related.

The truth is it is harder to do things right for bash.

Couldn't agree more.

Update point 3:

(future version) partition management (something like lvm with snapshot features?)

(future version) storage management (auto magically create mount points, includes portage sharing, allocate partition with disk manager like LVM)

ok

The truth is it is harder to do things right for bash.

Do you want me to migrate everything to AdaScript? Though it would require a GNAT install on the host.

[globalcitizen]

If we skip out on bash then we destroy too much portability. So it's a non-option, unfortunately.

[specing]

yes :(
