Bug#934463: initscripts: consider taking over hwclock policy machinery

[Mark Hindley]

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
