Hi Jonathan,

For some reason I did not receive your email:

This is for Guix System only.  Did you mean that it would be problematic
if you were running openSUSE in dual boot?

Btrfs has many benefits over Ext3:

it offers compression to about 30% on average, it supports subvolumes,
snapshots and snapshot syncing, and much more.

For all these reasons I believe Btrfs is a good default for the OSes of tomorrow! :)
