Bug 286233 – genkernel includes and loades raid and nfs modules

• Product: Gentoo Hosted Projects
• Status: RESOLVED WONTFIX

[Description Daniel Troeder 2009-09-24 14:04:03 UTC]

genkernel-3.4.10.904 includes all md-modules I have compiled as modules (md_mod dm_mirror raid10 raid456 raid1 raid0) into the initramfs, though I configure DMRAID="no" in /etc/genkernel.conf and my cmd line is
$ genkernel ramdisk

The modules are also all loaded when booting. (I really don't need them: I can unload them afterwards.)

Also the NFS client modules are included and loaded without having requested "--netboot". (And why is the "fuse" module there?)

Reproducible: Always

Steps to Reproduce:
1.$ genkernel ramdisk
2.$ gzip -dc /boot/initramfs-genkernel-x86_64-2.6.30-tuxonice-r5.mayo.nofb | cpio -t | grep 'drivers/md'
3. reboot
4. $ lsmod | egrep 'raid|dm|md'

Actual Results:  
$ gzip -dc /boot/initramfs-genkernel-x86_64-2.6.30-tuxonice-r5.mayo.nofb | cpio -t | grep 'drivers/md'

[Comment 1 Andrew Gaffney (RETIRED) 2009-12-27 00:39:16 UTC]

The DMRAID option controls the building of the tools. It does not disable support in the resulting kernel. If you want to do that, invoke with --menuconfig and disable it yourself.

The NFS code came long before the --netboot options existed. They are mostly unrelated and you can remove the NFS client modules the same way as above.
