Hi all, I've built a custom kernel, based on the 2122 source. The distinctive feature of this kernel is the lack of support for loadable modules, all required drivers and features are compiled in. I'm also using LVM on that system, which leads to the issue that the machine won't boot: the kernel panics after failing to find the root device. In grub.conf it is listed as root=/dev/VolGroup00/LogVol00. I suspected that for booting with / on a logical volume some extra functionality would be required that needs to be put into the initrd. Unfortunately, I have been unable to make an initrd, mkinitrd insists on a module tree. If I "steal" the initrd from the stock 2122 kernel, the machine boots fine. How can I make an initrd for a kernel with no modules and no module support? One that just contains the functionality to boot an LVM system? Cheers Steffen.
