Hi, Harald

Thanks for your fix, but I'm still worrying about below code:
-ConditionPathExistsGlob=|/etc/cmdline.d/*.conf
-ConditionDirectoryNotEmpty=|/lib/dracut/hooks/cmdlin

Is the above Conditions 'or' or 'and' relations?
will it just skip cmdline service in case any of the conditions do es not match?

If above is true then I'm still worrying about we will cause more problems. 
grep "inst_hook cmdline" shows a lot of stuff which is not limited to parsing 
/etc/cmdline.d/*.conf, such as:
04watchdog/module-setup.sh:    inst_hook cmdline   50 "$moddir/watchdog.sh"
40network/module-setup.sh:    inst_hook cmdline 91 "$moddir/dhcp-root.sh"
96securityfs/module-setup.sh:    inst_hook cmdline 60 "$moddir/securityfs.sh"

Even for hooks parsing cmdline, the cmdline params are not limited to 
/etc/cmdline.d/*.conf, they can also be specified in grub cmdline, isn't it?
