I think I've managed to recover the vast majority of my files:
$ sudo cp -a avd var
/run/media/niko/3ea0705c-21c9-4ba9-80ee-5a511cb2a093/nvme0n1p6/

cp: snapshots/images/3/snapshot/OSX-KVM/BaseSystem.img: recupero delle
informazioni degli extent non riuscito: Errore di input/output
The only valuable thing I've lost seems to be an hackintosh vm I use for
development, but I can create another one.

This error is weird instead, considering it's mounted ro it shouldn't
complain about no space being left.
By the way I didn't get any kind of I/O error while restoring avd, home
or images with btrfs restore: what's the difference with ibadroots?
