initrd vs kernel initrd= - ve2tmq - 2016-05-03 13:28
Hi
Some time I can load kernel the initrd like that
kernel /some/kernel
initrd /some/initrd.img
Other time doesn't works. I have to pass initrd as kernel parameter like
kernel /some/kernel initrd=/some/initrd.img
What is the difference between initrd command and passing initrd parameter to kernel command?
thanks.

On a UEFI system, you will need to include the "initrd=..." kernel command-line parameter. The Linux kernel's EFI stub uses this parameter to find the initrd image.
On a BIOS system, you do not need the "initrd=..." parameter, but there is no harm in including it.
In general: always include the "initrd=..." parameter. That way, your script will work on both BIOS and UEFI systems.
