Description parafin 2012-01-30 21:41:57 UTC

All current sys-kernel/genkernel versions (up to 3.4.24) doesn't include "linear.ko" kernel module into initramfs when run like this:
genkernel --mdadm all
So if you want to use linear MD array as root device, you have to either use --all-ramdisk-modules option or compile linear RAID level into kernel. It seems unlogical to me, that all other RAID types are supported by default and linear gets left out.

Reproducible: Always

Steps to Reproduce:
1. genkernel --mdadm all
2. try booting with root filesystem on the linear MD device
Actual Results:  
boot fails because specified root device doesn't exist

Expected Results:  
boot should succeed

Actually --all-ramdisk-modules isn't even enough, you have to add doload=linear kernel parameter.
