Indeed, nice catch, and thanks for the patch (and for filing the bug
report). While I don't quite like the hardcoding of the filenames, this
is something that was already implicitly done by the system libc
(including chroots and similar).

I'll be queueing this as part of the greater refactoring for the
dpkg sysusers support, and will probably add a way to override those
pathnames externally to mitigate this hardcoding.

Thanks,
