By adding all needed options to rootflags="..." (modify
GRUB_CMDLINE_LINUX_DEFAULT and possibly GRUB_CMDLINE_LINUX_RECOVERY
in /etc/default/grub; you can use yast for it).

Otherwise it is functional gap between non-systemd and systemd
enabled dracut. Without systemd dracut will actually mount root
read-only, then fetch mount options from real root /etc/fstab and then
remount real root read-write using correct options. This all got lost
when converting to systemd.
