Do I need to provide 3 or 4 numbers for mkinitrd as kernel version?

Question

Suppose the kernel is 2.6.32.9:

mkinitrd   /boot/initrd_2.6.32.9.img   2.6.32.9

Or

mkinitrd   /boot/initrd_2.6.32.img   2.6.32

Which one?

Answer 1

You must put in the full kernel version as given in one of the subdirectories of /lib/modules as the second argument. The first argument can be any filename of your choosing.
