Description D. Danner 2016-12-15 16:05:49 UTC 
When building an initramfs, genkernel-3.5.0.6 wrongly modifies the kernel
configuration, resulting in a non-bootable initramfs in specific cases.

For example, setting CONFIG_BLK_DEV_DM=y gets reverted to =m by genkernel if
LVM support is requested in genkernel.conf. In case module copying is not
enabled, the initramfs will end up without any LVM support and
probably won't boot.

Other options are affected as well.

This seems to have been introduced in 3.5.0.1 by commit f9324a84, when the sed
command was changed so that settings are forced to =m even if they're already
enabled.
