I also have a snippet in my .profile to use GUIX_DAEMON_SOCKET to ssh back to the head node to use the guix-daemon there, which keeps all the guix stuff on one machine and easier to manage and make sure the same software is available on all the machines. --=20 Efraim Flashner =D7=A8=D7=A0=D7=A9=D7=9C=D7=A4 = =D7=9D=D7=99=D7=A8=D7=A4=D7=90 GPG key =3D A28B F40C 3E55 1372 662D 14F7 41AA E7DC CA3D 8351 Confidentiality cannot be guaranteed on emails sent or received unencrypted --dvPmpoeHBo8p8Lwq Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEoov0DD5VE3JmLRT3Qarn3Mo9g1EFAmVe8eIACgkQQarn3Mo9 g1G2JBAAi/ntg4mjYZonNeRYHyaMYydIltwc8LoONaaHJbEEEMmMMR5RcFpHyXMa R85Sfb2IkCBKDkKccFsE2tGrGgwhccsvQSP+hVlaWfedhm61bWujcFJ2/h0o9++M wUKaXqPRiXmgtiGWVX9HJsvgmslldB1wgAQmADtD7Is6ATkEfArpKkkhkVjAKjSS 1ARyYBBxUtzpbsN8bjcSRXUTAc9peqv8ja47YfdXVrgz74y9hQJ676efASg22KLt hTdCWBwdSMdYGuznxPX6TNsjAiHm1dmf95WQEO+E0beD7UprQwK2JMXSmCGCt2qK tB3DncRoEfQCghMGvsZbjybYJUzpI2UV5wu64D+JwvAB5vDi9mS/jAvV8aBiG5BH MdNXX09U86+Bed6wZfN/k3NwXkch7ulOCH73YoWoA93ZAegHO4SkpzPIV0wocl5p 2KOP58+Dt514VTc566+xRKn4w0vWU2KxoYwaaNRbSlkO6tPZo+aQZtHFhKdK+/7b lTX8nvOvpUSyEIcONA5SGrrt4AX7N+v8Z0s86zM5j03F7VWFSRrUK0E3zrrQfSsm /Cjf6d6b607tvyGjxZ8lV/ktEQzkEWv136q3tSJQxUfXByVrxxnH2ymkwpr60jbS gJmwRt00pbXj7b2lhyr6KkCsggMT/oA//f4OrAtDmJEal7S4gy0= =1y4F -----END PGP SIGNATURE----- --dvPmpoeHBo8p8Lwq--
