Currently in Guix it's impossible to have a subvolume for the store and an encrypted subvolume for /home. In order to have an unencrypted root and an encrypted /home, we must put them on different _partitions_ so that we can crypt /home with LUKS. This has the big downside of imposing a fixed size at creation time. With ZFS, it would be possible to an encrypted /home without encrypting /gnu/store and without fixing the size at creation time. =2D-=20 Pierre Neidhardt https://ambrevar.xyz/ --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEUPM+LlsMPZAEJKvom9z0l6S7zH8FAl7E+3YACgkQm9z0l6S7 zH+q/gf/Y4OXSVmiAbpHGseH64md/cN/W6U03lCvqQDRd4MQhQ7+DhaPugTS1iOj sqOewZOl4c/ub1vLpJL2bunPjzwwh2TKETXwa71a3/k7siluBK+YKrrKFEy+2y8z n97RFJdVNiq8dc61+xMtFqZkVnTqNyBUdt087sWZ+AlUQuNQx8xvUvufnby6CQIK Zec0TUJKLrB1dTW8q0Z2E3SH/vpDCZ8X7Vj8lPhL6webNLHnjr/J+GcRJaUkiXkD IdJtkMU1dzxIOtnL8NeXOYzRtoZ00QAsUBM+ForIQnJQF+BXBjA6t+oWTTJ7Js3V gtluE8/3hf/rLnSqRAP1Ub62WZv4cQ== =1c2P -----END PGP SIGNATURE----- --=-=-=--
