Yes, I am using LVM nowadays. Even with BTRFS. Gives more flexibility for
example to test BCacheFS on my laptop once I have a 6.7 kernel that
actually does hibernate on the laptop, 6.7-rc4 still is broken in that
regard. But for desktop systems I just give 50 GiB to / meanwhile and
never ran into a space issue there so far. Not even with tons of flatpaks
installed for various reasons.

Currently 17 GiB of 50 GiB usage on BTRFS with zstd compression. And that
is with quite some flatpak applications including their runtimes. Just
Devuan with KDE Plasma, Firefox, Libreoffice, the usual stuff all from distro
packages just gives about 3-4 GiB of usage. So 50 GiB is *a lot*.

Best,
