The optional I<TARGET> argument can either be the path to a directory, the

The optional I<TARGET> argument can either be the path to a directory, the path

as I<TARGET>, optionally applying a compression algorithm as indicated by its

filename extension. If I<TARGET> is C<-> or if no I<TARGET> was specified,
|

then an uncompressed tarball of that directory will be sent to standard

output. When B<mmdebstrap> creates a tarball it also stores extended

attributes. To preserve the extended attributes, you have to pass B<--xattrs

--xattrs-include='*'> to tar when extracting the tarball. If I<TARGET> is the

output in any other mode than B<sudo>, then its contents will have wrong
