I looked a bit at the code for dpkg, and does indeed do it wrong.
Unfortunately, just patching it to do lchown instead of chown will fail
(at least on i386/2.0.x). I'd consider this a bug in libc. Anyway,
dpkg needs to call lchown() instead of chown() since that is really what
it wants to do. libc should be fixed to call chown() for lchown() iff
lchown() fails with ENOSYS. The interim fix is probably to have dpkg
call chown() iff lchown() fail with ENOSYS.
Who wants to file the bug reports?
