What happened to my machine?

[Brian Sturgill]

Hmmm... why would I have a whole new bizarre name to handle logical volumes?
Besides, logical volumes have been around for a very long time.
What sort of person thinks: /dev/mapper/dobby--vg-root
Is even marginally a good device name?
What happens if I rename "dobby" to "winky"?

As to "snaps ... don't pollute the system". It looks like they've polluted
my system to me.
Seriously, Ubuntu keeps putting more and more things in snaps.
My list is only that small because I have been consciously removing snaps
when I can.
If every major package was in a snap there would be hundreds of "df"
entries.
Why would anyone think this is a good idea?

And who would design a modern packaging system that makes you stop running
the app before it can be upgraded?  Imagine what it would be like once
there are hundreds of snaps installed!
All of them tell you to exit the app for upgrade.  At least Windows and
MacOS only make me reboot.

Look carefully at the "disk free" output... not one of them is an actual
disk device.
This is worse than systemd (which is responsible for /run/user/1000).
