Comment # 1 on bug 1206781 from Antonio Feijoo

This looks familiar to me, I think this is a duplicate of bsc#1200710:

[    2.233902] jobs dracut-pre-udev[452]: sh: /sbin/sysctl: No such file or
directory
[    2.234413] jobs dracut-pre-udev[451]: modprobe: ERROR: Error running
install command '/sbin/modprobe --ignore-install sunrpc  && /sbin/sysctl -q
--pattern sunrpc --system' for module sunrpc: retcode 127
[    2.234413] jobs dracut-pre-udev[451]: modprobe: ERROR: could not insert
'sunrpc': Invalid argument
