That is interesting. Something must been changed here. Do you use some partitions for both gentoo systems? Not the root, just like boot ESP partition or home. --=20 bobwxc --E6R4RJttG5PvW2DPigof1yS1HvMmmSoFl-- --k3ihw82OK2zNvFjz2UoJsGt4iUXla3qLj Content-Type: application/pgp-signature; name="OpenPGP_signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="OpenPGP_signature" -----BEGIN PGP SIGNATURE----- wnsEABYIACMWIQT2RVx6COimNyTG1Z426U6rtT5RawUCX9zYBwUDAAAAAAAKCRA26U6rtT5RawY+ AP0UilMvX05XppJJnWfnYuIEbXEOFfKq3WNK0jsEUM9u+wEA3jCitP5iHd/O7fmylhyivAMZH5hv 4k2Forw/ZKB8iQI= =mIXX -----END PGP SIGNATURE----- --k3ihw82OK2zNvFjz2UoJsGt4iUXla3qLj--
