comment Synchronize clock with NTP while online, and with RTC while offline?
This is the kind of solution I had in mind when I wrote my previous comment. Also, if the system clock is currently in sync via ntpd, you can use hwclock to measure and set a fairly precise drift rate for the RTC.

comment Synchronize clock with NTP while online, and with RTC while offline?
As I understand it, a combination of ntpd and hwclock already allows you to do all of these things.

comment rm on a directory with millions of files
find -delete tends to cause too much I/O and easily impacts production performance. Perhaps with ionice.

comment How to kill a <defunct> process with parent 1
@AndrewH I'm not sure SIGKILL depends on a signal handler in the target process, but it's true that the typical kernel will ignore a SIGKILL to init. However, should you run out of cooler ways to trigger a kernel panic, I think you will find that on most Linux systems a SIGSEGV will do quite nicely.

comment Encryption over gigabit carrier ethernet
I think part of the point is that WANs and LANs are growing a lot closer together technology wise. About line costs, around these parts, the cost of upgrading from virtual wire to dedicated wire/frequency (where MACSec is obviously fully supported) is a LOT less than acquiring dediacted L2 encryptors. We're talking an order of magnitude.
