My main concern is the possibility of data loss. I don't know how much is FUD and how much is legit so to me it seems safest to see what OpenSuSE uses and to mimic that a bit (in terms of not using most of the features available). That said, I use btrfs with no subvolumes with compression turned on and I'm pretty happy with that. Two more things: /var/guix/db should probably have CoW disabled, as should /tmp would the deduplication of btrfs be "better" than the deduplication from the daemon? --=20 Efraim Flashner =D7=90=D7=A4=D7=A8=D7=99=D7=9D = =D7=A4=D7=9C=D7=A9=D7=A0=D7=A8 GPG key =3D A28B F40C 3E55 1372 662D 14F7 41AA E7DC CA3D 8351 Confidentiality cannot be guaranteed on emails sent or received unencrypted --GV0iVqYguTV4Q9ER Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEoov0DD5VE3JmLRT3Qarn3Mo9g1EFAl7TYvIACgkQQarn3Mo9 g1H+Cg//YpbDdN3NPulrM+nGXxBZTit1Wky4NJUhSU4JDsZSZLwR5jOZpUTwXth1 tIt+3T4FrBCQJ1UgAdu4/eXi8AmZnjitByfpY3oSMOkedAF1nYiHh5O0vIzgXjaK A6h5GH2s3fPYZAYVCLfoOJcRJdS/yVT6CYKiX5tZ1Sen3RYdOJAKKEsYS0414+NQ pogG96VThVezkulY6s1c52YpnxznMig+Rdi9KiCasc6RIppOm1z1RT22PqZfK0cQ k9U1CwHhsa+WokiexupliNZotSYn0g20AGnF+HL+3JhTjPg21BWMgrgd78DYhqLw myT+lo/emYl0MJa0J1gYfdXtOAMmenskp54PmYBJFjkekGCgFOwmdvLW91lYbJC/ Wq9Ld7jQp7wuuKzYQenWYJLQdBZaTXraZpqjCxZ8FAx04EYa5czjv/6z+/pu/JLe Fn42hDmQLsMSsUaD8ZkInfHrTuLX9StesNoh/t/flYbd2gwX/qoWqA/M0a3IBjvi YzQWprMSQC7h1vWQTOJTMWzT0DqIWFRMy5eA8wuefN9EkH7XfQFQN6fQlkec5L4O 2qQJah7ba9spilNnlaeeQ99RBHT0MEya0lmUecksPRu3jmJljAxlJCNyrF7rZ8t7 xH3hJ/m32aKpERJVZo55oz7dhId4INqtUh69zcVXzmav/IDqP/4= =kKwm -----END PGP SIGNATURE----- --GV0iVqYguTV4Q9ER--
