I'm trying to get an external USB hard drive enclosure to mount from fstab (yes, I know there are easier ways, but I'm doing this in preparation for a setup later where I can't use the easier ways), and my kernel is ignoring the rootdelay option. I'm using the default Arch kernel, and here's the section in menu.lst that boots the kernel:
# (1) Arch Linux
title Arch Linux Wait
root (hd0,0)
kernel /vmlinuz26 root=/dev/disk/by-uuid/89391563-cee6-4efb-b1e2-fd5a533bdaf4 usb-storage.delay_use=1 rootdelay=120 ro
initrd /kernel26.imgNow, I don't actually want a 2 minute root delay, but I tried 10, 20, and 30, and couldn't observe any difference. If I understand this correctly, the system should boot, load modules from the initcpio image, and then sit there for two minutes before running the Arch boot scripts, which are on the root filesystem. Instead, the system boots normally.
I've gotten it (the external enclosure) working with the usb-storage.delay_use option because it spins up when the BIOS runs, so its hard drive is ready by the time the kernel starts loading. I've added usb to the HOOKS and usb_storage to MODULES in /etc/mkinitcpio.conf, and I regenerated the initcpio images by running `pacman -S kernel26`. However, in the target system that this drive will be deployed to, the BIOS time is very short, so I don't know if this trick will work.
Why is the kernel not adding a rootdelay like it should?

Perhaps the term ...rootdelay=8... should be added after the read-only (ro) term?
Prediction...This year will be a very odd year!

rootwait after rootdelay=8 should help
