Thank you both. I really do want to believe that this is not an issue with systemd &/or the Ubuntu 16.04 base, but is instead only a bug in the CD applet. However, here's why i'm still anxious.
The very first Plasma5 VM i created, to begin my self-education of how Plasma5 differed to KDE4, was Kubuntu 16.04 (i installed this on 13/5/16] . It came as a shock to me that Kubuntu itself, via its native System Tray Notifications widget, consistently told me that a restart was needed, most of the time that system updates occurred. That was not CD telling me, it was Kubuntu itself.
To check my memory, after reading your replies, tonight i fired up my Kubuntu VM. As i'd not run it for a while, there were a large amount of updates needed. After it installed them, this happened:
I rebooted, then found another 7 updates were needed. Once again, after installation, its Notifier said to restart, so again i did. Tonight's experiment is entirely typical of my previous months of playing with Kubuntu 16.04. As i said in my initial post, this behaviour shocked me; Mint 17.x never did this.
Now its true that Maui in my Tower has not told me i need to restart, & [as best i can recall], neither has Mint 18 on my Lappy... instead in both cases it is CD telling me. However, how then can we explain the Kubuntu behaviour? So you see, my anxiety is that Kubuntu is obviously based on Ubuntu 16.04, as are both Maui & Mint 18. Ie, how can i tell for sure that it is only a CD applet bug, rather than the CD applet is faithfully responding to an underlying message from the OS... the same message that is directly available in Kubuntu?
If you tell me that it is a certainty no restarts are needed, then i will stop worrying, disable that nuisance CD applet, & forget all about this... only that Kubuntu behaviour still would remain unexplained...
