In my experience, splitting the storage demand into a new folder
location simply hasn't been available, or would have required a lots of
service downtime for data movement and reconfiguration.  Runaway log
files, growing databases, app upgrades that won't fit in the original
root FS -- not solvable with space in a new mount point.

LVM solves real problems.  And it can also solve problems your way,
making new volumes for new mount points, too.  I highly recommend it for
all bare-metal systems -- servers, workstations, laptops.  It's the
Leatherman for Linux.
