I see there was a discussion nearly 10 years ago about all the "noise"
(entries for non-physical "mount points"). Since that time with Snaps
and Flatpaks, the output has gotten even worse.
Rather than trying to include all of the exclusions in a single switch,
couldn't a switch be added to only show actual, physical
disks/partitions/volume group LVs? Personally I think that should be the
default, but I recognize that would break various scripts and aliases
for people.
The problem with making aliases to exclude these, or running alternate
utilities, is that only works on your _own_ machines; if you have to
administer other machines your aliases/alternative won't be there.
Perhaps a switch like "--po" ("physical only", although I could think of
a different phrase to fit it).
