rpc bind errors when disabling IPv6

I'm using the kernel command line parameter ipv6.disable=1 in my boot loader (systemd boot) to disable IPv6. However, with that option, I now get these errors in the journal after booting up. Jul 09 02:38:48 arch rpcbind: cannot create socket for udp6 Jul 09 02:38:48 arch rpcbind: cannot create socket for tcp6 Jul 09 02:38:48 arch rpc.statd: Failed to create listener xprt (statd, 1, udp6) Jul 09 02:38:48 arch rpc.mountd: Could not make a socket: (97) Address family not supported by protocol This is Arch Linux 4.14.53-1-lts #1 SMP Tue Jul 3 16:27:18 CEST 2018 x86_64 GNU/Linux What are the consequences of these errors and how do I resolve this while keeping IPv6 disabled?
