Here, it works as expected.

        tlash pyarch> inventory -p
        address@hidden
        address@hidden
        address@hidden
        arch/__init__.pyc
        arch/_tla.pyc
        arch/arch.pyc
        arch/errors.pyc
        arch/util.pyc
        tlash pyarch> 

Using 1.2.2rc2.

The --names option just enable "names" tagging method and overrides the
setting in =tagging-method.

That's useful to disable untagged-source classification, since a file is
never untagged with the "names" tagging method.

This would conflicts with the contract of "tla inventory" as I
understand it, which is "list all arch-controlled files". Symlinks are
version-controlled, traversing them would not expose the actual
inventory.

GNU tar has no --follow option.

If I understand you well, you want to export a Arch tree (a la make
dist) by traversing the symlinks. Actually, you want to export _part_ of
an arch tree...

You could do it in several steps:

1. Export your _whole_ tree using something like

        tla inventory --whatever --nested | \
          cpio --pass-through --link --make-directories ../export-stuff

2. Prepare the tarball

        cd ../export-stuff
        mv build javafrob-1.0
        find -follow javafrob-1.0 | tar cTzf - javafrob-1.0.tar.gz

Or something like that.

Anyway, your approach seems broken because if "--whatever" is source,
then you'll probably miss your build files (which _should_ not be
source) and if it is --precious or something else like that you will be
likely to get random crap precious files as well.

I guess there is probably a better way to organize your source trees.
