I don't understand this. Merely having a libary installed should not imply any userspace actions. If some packages need device mapper functionality, they need to depend on dmsetup, not just libdevmapper. We've seen quite a lot of upgrade failures due to this circular dependency, so it's clearly a problem: | Unpacking dmsetup (2:1.02.90-2ubuntu1) over (2:1.02.77-6ubuntu2) ... | Preparing to unpack .../libdevmapper1.02.1_2%3a1.02.90-2ubuntu1_amd64.deb ... | Unpacking libdevmapper1.02.1:amd64 (2:1.02.90-2ubuntu1) over (2:1.02.77-6ubuntu2) ... | Preparing to unpack .../libudev1_219-7ubuntu6_amd64.deb ... | Unpacking libudev1:amd64 (219-7ubuntu6) over (204-5ubuntu20.15) ... | Processing triggers for man-db (2.6.7.1-1ubuntu1) ... | Setting up libudev1:amd64 (219-7ubuntu6) ... | dpkg: dependency problems prevent configuration of libdevmapper1.02.1:amd64: | libdevmapper1.02.1:amd64 depends on dmsetup (>= 2:1.02.90-2ubuntu1); however: | Package dmsetup is not configured yet. | | dpkg: error processing package libdevmapper1.02.1:amd64 (--configure): | dependency problems - leaving unconfigured This then causes a trail of followup errors, like failing to configure libcryptsetup4, systemd-sysv, and init. IMHO the cleanest solution is to drop libdevmapper1.02.1's dependency to dmsetup entirely. For fixing the upgrade bug it should be sufficient to downgrade it to Recommends, though, to hint apt into ordering it correctly.
