Hello The installed-os test is failing because the image closure is (again) bigger than the allocated 1.4GiB in the test partition. --8<---------------cut here---------------start------------->8--- guix size $(./pre-inst-env guix system build gnu/system/examples/bare-bones.tmpl) --8<---------------cut here---------------end--------------->8--- reports 1397.3 MiB. By reverting this commit 0eed77127592323d89f56c215a15374a1aaae110 (introducing an extra glibc to %default-locale-libcs), it drops down to: 1305.5 MiB. Now multiple options: * Revert this commit. * Find other system closure improvements. * Up the limit to 1.5GiB. WDYT? Thanks, Mathieu
