[pkg-cryptsetup-devel] Bug#952703: [cryptsetup] needs breaks on old cryptsetup-bin

[jnqnfe at gmail.com]

Package: cryptsetup
Version: 2:2.2.2-3

I've noticed that selectively trying to just upgrade the cryptsetup
package via `aptitude upgrade cryptsetup` fails with the following dpkg
error:

```
dpkg: error processing archive
/var/cache/apt/archives/cryptsetup_2%3a2.2.2-3_deb (--unpack):
 trying to overwrite '/usr/sbin/luksformat', which is also in package
cryptsetup-bin 2:1.7.0-2
```

I expect you forgot to place a suitable breaks on the older packages
after the reorganisation.

I experienced this running the above command whilst updating cryptsetup
in a live-disc environment that has a much to old version (don't worry
my actual installs are uptodate!). Clearly what should be expected from
a targetted upgrade specifying just `cryptsetup` and not `cryptsetup
cryptsetup-bin cryptsetup-initramfs` should be that it either pulls in
all three as necessary upgrades or at least complains about version
conflicts. It should never just fail like this.
