Bug 269042 – sys-kernel/genkernel-3.4.10.904: doesn't include dm-crypt module in initramfs despite --luks switch

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Marios Andreopoulos 2009-05-08 16:46:24 UTC]

Genkernel (3.4.10.904) when called with --luks switch doesn't include in the initramfs the dm-crypt (dm-crypt.ko) module which is necessary for the kernel to open encrypted partitions.

A workaround is to compile dm-crypt into the kernel but I believe the expected behaviour is for this module to be included if found, such as the rest device mapper modules.

Reproducible: Always

Steps to Reproduce:
1. emerge =sys-kernel/genkernel-3.4.10.904
2. genkernel --install --luks --menuconfig all
3. In menuconfig set device mapper and crypt target to be compiled as modules.
Device Drivers -> Multiple devices driver support (RAID and LVM) -> Device mapper support <M> AND Crypt target support <M>
4. zcat newly_created_initramfs | cpio -t | grep dm-crypt.ko 
Actual Results:  
The last command gives empty output.

Expected Results:  
Grep the dm-crypt module:
lib/modules/version/kernel/drivers/md/dm-crypt.ko

This has been fixed in git.

I have yet to learn searching in git. :(
genkernel devs feel free to change the status of the bug. Thanks for your efforts and time on genkernel!

Just emerge =sys-kernel/genkernel-9999. That will do a git checkout.

Confirmed to work with sys-kernel/genkernel-3.4.10.907.  Closing.
