Bug#46748: dpkg: [hurd] please lock full file

[Marcus.Brinkmann@ruhr-uni-bochum.de]

Package: dpkg
Version: 1.4.1.11
Severity: important

Hello,

this is one of the many things that needs to be fixed for the Hurd, it is
not release critical for Linux.

Partial file locking is currently not supported in the Hurd. We would like
to fix this, but until this is implemented, please lock the whole file. As
it is a zero length file, this doesn't make a functional difference at all.

Thanks,
Marcus
