It seems to hang the system test in a part I cannot change (so it's not ins= ide the test script). In order to reproduce, start with guix master commit 898fbb60b2354e82e5b7f259b44dbfed112a83aa--or any recent Guix master commit. So far it's still "fine"-ish: $ make TESTS=3D"nfs-root-fs" check-system [... works fine and eventually fails because port 20001 is waited for but is never opened by the server--so far so good] Now edit gnu/tests/nfs.scm to change ;(rpcmountd-port 20001) to (rpcmountd-port 20001) in order to fix the problem above--or so I thought. $ make TESTS=3D"nfs-root-fs" check-system [... hangs in first VM--without even trying to start up the NFS server VM (= as far as I can tell)] What is going on? Also, how to debug this? (same happens when enabling (rpcstatd-port 20002) only. Also, doesn't rpcstatd have TWO ports--one to broadcast and one to listen? How does one set up both using the operating-system configuration?) --Sig_/cDiT.ZdzEmJ=AFoTHpLtYuk Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCgAdFiEEds7GsXJ0tGXALbPZ5xo1VCwwuqUFAl9eeG4ACgkQ5xo1VCww uqX8ywgAkAPX6aAJNTjEdco0xrH16yucp92NwomwJ78Tdk+py2YYMjxoOlz3NgsZ dznH+M2kJE/ObMpSq+Q0LzfpTpXqxuhIhDPq+nWVaok/RoVXYFEFo9NYqq4yt6qk U+fUtQYYAiuwiih34Olrz8ncIi+YwX0UEoxKXl/5ai+nHf3DWLnjKSKT3MMiS1b3 eUGBcpgdtKG+7MPPn/8GMMkjuCRQZW6v1owofH8SUjISxBMEHmNvUnKP6rAQ39Mb x9EAhJNcNJexMzb4m802pO4F6gfjvmJxJmdbN4wvQjnm6jkBW7hx+o0W2NiMdxqj KkS4QSHOiFustW1RzkuiIOhQRJo5iA== =qTlP -----END PGP SIGNATURE----- --Sig_/cDiT.ZdzEmJ=AFoTHpLtYuk--
