Question about mkinitrd in Red Hat

awkward · 07-02-2007, 10:59 AM

Hi.

After reinstalling Red Hat, I needed to recompile a driver for my Qlogic HBA. I went through and recompiled the driver, but when I ran the mkinitrd command, I received a message stating that the image already exists.

Why would I receive this message?

Any help would be appreciated.

The clue is in the question

mkinitrd will not let you overwrite an existing ramdisk image (such as the default initrd file installed in /boot) unless you use "-f" option.

Since the file is critical to the boot process, personally I make a copy of the old initrd file first, in case the new one doesn't work. You can always select a different initrd by interrupting the grub boot sequence and editing the initrd option.
