Hello,
I sent the email below as a bug report, but I should probably have sent
it to guix-devel instead.
The gist of it is that libaio on core-updates doesn't build on guixp9
because its testsuite (intentionally) catches a kernel bug.
I can do an “apt-get update && apt-get upgrade” to fix the problem but
since I don't have console access to the VM I'd need someone else to
reboot it just in case it doesn't come back on its own...

Thanks
