Package: live-build
Version: 2.0~a22-1
Severity: grave

A package upgrade from 2.0~a21-1 to 2.0~a22-1 fails with:

Preparing to replace live-build 2.0~a21-1 (using .../live-build_2.0~a22-1_all.deb) ...
Unpacking replacement live-build ...
dpkg: error processing /var/cache/apt/archives/live-build_2.0~a22-1_all.deb (--unpack):
 unable to install new version of `/usr/share/live-helper/data/debian-cd/squeeze/mipsel_netinst_udeb_include': No such file or directory

The reason for the failure is apparently the 'squeeze' symlink in ~a21 is
replaced with a directory in ~a22, which policy prohibits in 6.6.4:


    A directory will never be replaced by a symbolic link to a directory or
    vice versa; instead, the existing state (symlink or not) will be left alone
    and dpkg will follow the symlink if there is one.

As a workaround, remove the old package and install the new.

We should check in preinst if the symlink exists and points where it is supposed
to, then remove it before unpacking.  Also, preinst should handle putting the
symlink back if called with abort-install.
