  That isn't good!  Do you have any idea why this fails?  An strace
 or similar might help track it down...

  That seems like a reasonable approach to me, though as you say not
 a perfect solution.

  There should be a better way of handling this, but with the different
 installation methods (debootstrap, rinse, rpmstrap) this could be
 tricky.  I'd prefer something that mapped nicely to each other
 even it if was something like:

    exclude-packages = libc6-xen, less, bash

  For the debootstrap case that could be passed to "--exclude" cleanly
 enough.  For the other cases I think it is probably OK to ignore the
 issue for the moment.

  Off the top of my head I'm not sure why you need to specify "main",
 "universe", etc.  It should be sufficient to just have a package
 blacklist - but maybe I'm being dense...

  I'm glad it is useful :)

  There will be a new release once the rinse software makes it to
 Debian's unstable tree.  At that point I think I will remove all
 mention of rpmstrap - on the grounds that it is broken and will
 be superseded..
