Dunno exactly if it's dracut's or dash's fault but I suspect dash-0.5.10 as that was the part that has changed and reverting to a previous dash version fixes the issue. The problem is, that with dash-0.5.10 the initrd simply stops at some point. I can see the dracut version being printed during boot and the message about udev being started but then the initrd hangs.
This is my dracut config: # grep -Ev '^[[:space:]]*#|^$' /etc/dracut.conf.d/99_local.conf hostonly="yes" dracutmodules+="dash i18n kernel-modules resume rootfs-block terminfo udev-rules base fs-lib shutdown btrfs caps crypt lvm" hostonly_cmdline="yes" compress="xz" use_fstab="yes" root="LABEL=root" early_microcode="yes" i18n_vars="/etc/conf.d/keymaps:keymap-KEYMAP /etc/conf.d/consolefont:consolefont-CONSOLEFONT-FONT /etc/rc.conf:UNICODE"
