Speeding my mkinitcio

I'm trying to get rid of the udev hook in my mkinitcpio.conf. I'd like to only use the base hook.

So here is my modules list, which should be enough to run my system (according to hwdetect) :
MODULES="pata_acpi ata_generic scsi_mod ahci ata_piix ext3"

Unfortunately, when booting, the image cannot find my root partition.

I have a Dell Vostro 1500 with a SATA disk and the root partition is in ext3. How could I know which module I miss ?

Re: Speeding my mkinitcio

You can add "break=y" to the kernel params, to get a prompt while in the initramfs image. If you do this, you can then poke around and see what you need to see. Try "echo /dev/*".
Keep in mind, the klibc shell is VERY limited. This is on purpose.

Additionally, please post the output of "lsmod" on a booted system

Re: Speeding my mkinitcio

the /dev in my ramfs is almost empty : console, mem, zero... there is no hard disk.

Here is my lsmod >

I noticed the "libata" module at the end that was not present in my mkinitcpio.conf. I added it but it didn't change anything

Did you try the order hwdetect --show-modules-order gives you?

I think you need also sd_mod...

And without udev you have to setup the device nodes yourself..

Re: Speeding my mkinitcio

Ok, problem SOLVED !

punkeroso > I was missing sd_mod indeed.

buddabrod > You scared me. Fortunately there is something in initramfs which created the the root device automatically.

Thanks for the help.
