-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Package: src:zfsutils
Version: 8.1-4+squeeze1
Severity: serious
Justification: breaks upgrades, does not declare dependencies properly
Out of the zfsutils package are being built several shared libraries.
These do not bump any SONAME version or provide a symbols file. Hence,
shlibs generates zfsutils dependencies unversioned:
Depends: libbsd0 (>= 0.0), libc0.1 (>= 2.4), libgeom1 (>= 7.0),
libnvpair0, libumem0, libuutil0, libzfs0, libzpool0, zlib1g (>= 1:1.1.4)
That implies that zfsutils would work with any version of libnvpair0,
libumem0, libuutil0, libzfs0, libzpool0 installed. That is, however not
true. Upgrading zfsutils from 8.1 (Squeeze) to 8.2 (Wheezy) or any later
version breaks ABIs but does not pull appropriate dependencies.
Thus, users which do not do a full upgrade are left with broken zfsutils:
