<div>While these things are annoying, I'd be
happy(er) if the latest "upgrade" or two didn't break basic
functionality:</div>
<div><br>
</div>
<div>1. Clicking on a link in a Thunderbird
email usually doesn't open the link.</div>
<div>2. Clicking on a window doesn't bring
it to the foreground anymore. I have to click on the desired
program in the left vertical panel instead.</div>
<div>3. Doing "save as" frequently, perhaps
always, doesn't work properly anymore. I have to use "print to
file" as a workaround.</div>
<div><br>
</div>
<div>But I don't get Brian's weird df
output, it's the same as it's always been, for me.</div>
<div><br>
</div>
<div>I'd migrate elsewhere, but I do
business on this machine, and that scares me.</div>

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

<div>What happens if I rename "dobby" to "winky"?<br>

<div>As to "snaps ... don't pollute the system". It looks like
they've polluted my system to me.<br>
</div>
<div>Seriously, Ubuntu keeps putting more and more things in
snaps.<br>
</div>
<div>My list is only that small because I have been consciously
removing snaps when I can.<br>
</div>
<div>If every major package was in a snap there would be
hundreds of "df" entries.<br>
</div>
<div>Why would anyone think this is a good idea?<br>
<br>
</div>
<div>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!<br>
</div>
<div>All of them tell you to exit the app for upgrade. At least
Windows and MacOS only make me reboot.<br>
</div>
<div><br>
</div>
<div>Look carefully at the "disk free" output... not one of them
is an actual disk device.<br>

<div>This is worse than systemd (which is responsible for
/run/user/1000).<br>

<div>The dev mapper stuff is logical volumes, so you can add
and rearrange storage easier. All of the snap things are
snap applications you have installed, they have their own
little fake file systems so that they don't pollute the
system.<br>

<div>Seriously, what kind of device is
/dev/mapper/dobby--vg-root?<br>
<br>
</div>
<div>Just last week, it was constantly badgering me to
exit Firefox to upgrade its snap.<br>
</div>
<div>It said I had to do so within 12 days if I wanted
to "avoid disruption".<br>
</div>
<div>Sounded like some kind of organized crime racket.<br>
</div>
<div>I exited, waited, it complained again, (repeat 5
times)... finally told snap to upgrade it</div>
<div>manually, but cannot remember what worked... I
know it took like half an hour to figure it out.<br>
</div>
<div>Snap upgrade is too easy of course.<br>
<br>
</div>
<div>Really, I get less crap than this from Windows or
MacOS.<br>
