regularly requires dist-upgrade to do their frequent Kernel Upgrades,
because they change Version Numbers on, among other things, the vmlinuz
file. So, when I do "apt-get upgrade" on the remaining Ubuntu Laptop, I
regularly see things like,
>> root@EyeBlinkLenovo:~# apt-get -d upgrade
>> Reading package lists... Done
>> Building dependency tree
>> Reading state information... Done
>> Calculating upgrade... Done
>> The following packages have been kept back:

>> 0 upgraded, 0 newly installed, 0 to remove and 6 not upgraded.
But then, "apt-get dist-upgrade" gets me "new packages", where only a
"sub-version" is different. For example, when the "smoke clears" from the
dist-upgrade, my "vmlinuz", in my /boot directory consists of (among other
things)
>> vmlinuz-4.4.0-124-generic
>> vmlinuz-4.4.0-127-generic
Note that these are different Packages.
Now I know, that Ubuntu is aimed, at a less technical audience, but this
threw me for a loop (and came to the foreground, when I didn't allocate a
large enough /boot partition. I had to learn "apt-get autoremove" in a
HURRY!!! Oh well. I;m sure each of you have your own Administration War
Stories).
But this "Feature Creep" on the Linux Kernel, is why I am here now,
"upgrading" my Ubuntu Server Systems to Debian 9.4. Once again, Go Debian!)
So, once again, watch out for "dist-upgrade", if there's any "hint" of
Ubuntu (i.e. Mint, Elementary OS, and many others out there).
Word to the Wise.
