OK, will push.
The main problem is this error (while connecting to the build daemon
over a Unix-domain socket):
--8<---------------cut here---------------start------------->8---
In guix/store.scm:
270: 1 [open-connection "/root/guix/test-tmp/var/1123/daemon-socket/socket" #
#t]
In unknown file:
?: 0 [setsockopt #<input-output: socket 5> 65535 4098 12288]
ERROR: In procedure setsockopt:
ERROR: In procedure setsockopt: Protocol not available
--8<---------------cut here---------------end--------------->8---
I just checked, and pflocal (the Hurd’s translator that implements
AF_UNIX sockets) always returns ENOPROTOOPT for ‘setsockopt’
(aka. ‘socket_setopt’), hence this failure:
http://git.savannah.gnu.org/cgit/hurd/hurd.git/tree/pflocal/socket.c#n456
Can you test the workaround below?
Thanks,
Ludo’.
