% may be a low estimate of wasted disk space. I had a dir go from 54M
in a 1k block environment to 78M when cp'd to a 4k block system - that
is a 44% increase when moving to 4k blocks, or a 31% savings when moving
to 1k blocks... it was a $HOME and had a mix of file sizes.
Some dirs will see a 10

The default isn't 4k, it's 4k _if_ the partion is over a certain
size. Falling back to 1k for smaller siz

I don't disagree with your assessment that we should probably use 1k
block sizes for root partitions when they are under a certain size.
Remember that a lot of users just make one gigantic 2gig partition and
put everything on that.
Anyhow, you shold probably file a wishlist bug against boot-flop

Actually on my system all partitions are 1k:

What exactly is on your /-mountpoint? home? var? usr? opt? Everything?

Hi,
I found that of my 2GB root filesystem more than 10% is wasted because it has
been formatted by the potato installer with a 4K block size instead of 1K.
In other words if the same files are stored on a filesystem with 1K-blocks I
have other 200MB available.
This is the test I have done:
# m
