Comment # 5 on bug 873919 from Thomas Blume

In 13.2, dracut goes into the emergency shell on fsck return value 4:
See ./modules.d/99fs-lib/fs-lib.sh:

-->--
fsck_ask_err() {
    warn "*** An error occurred during the file system check."
    warn "*** Dropping you to a shell; the system will try"
    warn "*** to mount the filesystem(s), when you leave the shell."
    action_on_fail -n "(Repair filesystem)"
}

# inherits: _ret _drv _out
fsck_tail() {
    [ $_ret -gt 0 ] && warn "$_drv returned with $_ret"
    if [ $_ret -ge 4 ]; then
        [ -n "$_out" ] && echo "$_out"|vwarn
        fsck_ask_err
--<--

So, I guess it is kind of compatible with my patch.
