I identified three packages that don't ship a SONAME symlink and cause spurious creation and removal of this link by ldconfig. Spurious since the packages themselves don't call ldconfig, so another installation will trigger the ldconfig run - 2 seconds or 2 months later. As this makes the (dis-)appearance nondeterministic, this could produce heisenbugs that will be hard to debug. So better ship the link in the package and let dpkg instead of ldconfig manage creation/removal. libusb-dev is one of them (#706278), due to the /usr/lib/<triplet>/libusb.so -> /lib/<triplet>/libusb-0.1.so.4.4.4 link. The SONAME is libusb-0.1.so.4 and ldconfig will create /usr/lib/<triplet>/libusb-0.1.so.4 -> libusb.so The attached patch adds this link to the libusb-dev package: /usr/lib/<triplet>/libusb-0.1.so.4 > /lib/<triplet>/libusb-0.1.so.4 As libusb builds an udeb, too, this will probably have to wait for r1. libusb currently has a non-standard NMU version, we could fix this into 0.1.12-20.1 (or 0.1.12-20.2), but using the more canonical +deb7u1 suffix will be difficult. So I just incremented the "bad" version. Andreas unblock libusb/0.1.12-20+nmu2
