Andreas, I have prepared the necessary updates to src:sysvinit to incorporate the hwclock machinery in initscripts. Specifically the files
/etc/default/hwclock /etc/init.d/hwclock.sh /usr/share/man/man5/hwclock.5 /usr/lib/udev/hwclock-set /usr/lib/udev/rules.d/hwclock.rules Obviously we need to coordinate the transition and I will add Breaks/Replaces << the util-linux-extra version which drops the files. If util-linux-extra were to use it, my understanding is that rm_conffile only removes *unmodified* conffiles so user modifications should be preserved. But we might consider synchronised uploads to experimental to test and confirm. Best wishes Mark
