Hi, While working on Berlin today from a chroot, and with --no-substitutes used for guix-daemon, I wasn't able to complete the 'guix system reconfigure' step; it'd hand on a read call (seen using strace):
--8<---------------cut here---------------start------------->8--- statfs("/gnu/store", {f_type=BTRFS_SUPER_MAGIC, f_bsize=4096, f_blocks=26843282944, f_bfree=14069128626, f_bavail=14067391234, f_files=0, f_ffree=0, f_fsid={val=[0x4f5822b0, 0xf74cbbd4]}, f_namelen=255, f_frsize=4096, f_flags=ST_VALID|ST_RELATIME}) = 0 write(14, "\t\0\0\0\0\0\0\0\2\0\0\0\0\0\0\0006\0\0\0\0\0\0\0/gnu/sto"..., 152) = 152 read(14, "gmlo\0\0\0\0", 8) = 8 read(14, "\276\0\0\0\0\0\0\0", 8) = 8 read(14, "@ build-started /gnu/store/kv1gh"..., 192) = 192 ) = 12 write(2, "applying 3 grafts for guix-1.3.0"..., 48applying 3 grafts for guix-1.3.0-29.9e46320 ... ) = 48 read(14, "gmlo\0\0\0\0", 8) = 8 read(14, "\255\0\0\0\0\0\0\0", 8) = 8 read(14, "@ build-log 17291 151\ngrafting '"..., 176) = 176 \) = 5 read(14, --8<---------------cut here---------------end--------------->8--- After passing --no-grafts to 'guix system reconfigure', it could complete without any error. -- Thanks, Maxim
