[SOLVED]make mkinitcpio use each kernel with its own kernel cmdline

he guys i  hope your doing well , i need i functionality that requires a specific kernel cmdline , before continue i want to mention that i dont use bootloader and instead i use inified kernel image with its entry in the UEFI , mkinitcpio uses /etc/kernel/cmdline , i read in the wiki that its capable also of catching .conf files from /etc/cmdline.d , but for my situation i need each kernel with its own cmdline so i dont need to change it every boot , i.e for example /etc/cmdline.d/linux.conf /etc/cmdline.d/linux-zen.conf , as in the wiki mkinitcpio well catch all the cmdline and apply it , how to activate this behaviour .

According to the wiki you can edit the mkinitcpio preset for each kernel and specify default_options to include --cmdline=/etc/cmdline.d/linux.conf for the linux preset and --cmdline=/etc/cmdline.d/linux-zen.conf for the linux-zen preset.

Exactly right!   I use this method for booting however i have ReFIND installed as a final and 3rd option incase stuff goes south.   

My efi menu looks like:
Arch Linux EFI
Arch Linux EFI (Fallback)
ReFiND

I use the method trilby lists above to manage cmdline options in the first 2 entries.  I only ever touch refind in a system recovery situation.
